Why True RMS Meters in HVAC/R

If the loads you measure are controlled to do more than go on and off, you may need a true rms meter. Here’s why.

DC voltages and DC current values don’t change if there is no change in the load or supply. The formulas for power are very simple. Power=voltage X current.

AC voltages and currents change very quickly, even if the load isn’t changing. Formulas for power can be very complex. RMS values are used to be able to simplify the relationships of current and voltage to power on AC lines. RMS values on AC lines can be used in the same basic formulas as for DC.

The AC voltage for a 120VAC power line varies from 0 to +169V to 0 to -169V and back to 0. It does this cycle 60 times a second. If the load is a resistive load, like a heater, the current will go up and down exactly the same as the voltage. The “waveforms” (the plot of voltage or current vs. time) will look the same. They will be sine waves. Nice smooth waveforms that go, in the case of a 120VAC line, from 0 to 169V to 0 to –169V and back to zero, 60 times a second.

The convention for hand held meters is to display the value that’s “equivalent” to the DC value. By “equivalent”, they mean the value that will work in the simple power calculations for DC. This way, you can easily use the value in the same power formula: power= volts X amps. This is the “rms” (root mean square) value.

Most DMMs and clamp meters display the rms value for a sine wave. They call this “average responding, rms indicating”. The inner workings of the DMM measure the “average” value and then apply a multiplier to display a reading that’s equivalent to the rms value of a sine wave. In the example above, the rms value is 120V.

In HVAC/R, most signals are sine waves because most loads are AC motors. The shape of the voltage and current waveforms for AC motors are sine waves. For sine waves, an “average” measuring meter will give you the same exact reading as a true RMS meter.

However not all waveforms in HVAC/R are sine waves. Variable speed fan motors can have non-sine wave forms for voltage and current. Also some control signals and heaters. For these, in order to get a number that is equivalent to the DC value that you can use in power formulas, you need a “true rms” meter. This meter, deep down in its inner workings, actually measures the rms value, not the average. It requires extra circuitry and therefore cost more than a more common average responding, rms indicating meter. All true rms meters have a limited ability to accurately measure waveforms that have peaks that are much different from the nominal reading, specified as the “crest factor”.

In practice, the equipment manufacturer will specify when you need a true rms meter. If the service manuals say you need a true RMS meter, chances are there is a variable speed motor and you need a true rms meter. If the operators manuals don’t say you need it, unless you know otherwise (a variable speed fan motor, for example), you probably won’t notice a difference.

ATC1 K-Type Thermocouple Offers Easy Access and Fast, Accurate Readings for Pipe Temperature Measurement

Brea, CA, April 7, 2005 — Fieldpiece Instruments introduces a new thermocouple, ATC1, for the field service technician. Designed for easier, more accurate pipe temperature measurement readings than conventional styles, the new thermocouple works with Fieldpiece’s temperature accessory heads, superheat accessory heads, or other temperature instruments that useType-K thermocouples. It can read temperatures up to 400°F.

The thermocouples’ clamp-on design allows the technician to fit it directly on the sides of the pipe for easy attachment. The ATC1 is a pipe clamp thermocouple accessory that features a maximum 1 3/8” jaw opening, enabling easy access to virtually any location needed.

“The ATC1 was designed primarily to make taking suction line temperatures easier,” said Rey Harju of Fieldpiece. “Just clamp it on for a solid thermal connection to the suction line.”

The ATC1 can easily facilitate taking a superheat orsubcooling measurement on most residential and commercial refrigeration appliances or air conditioners. Because of its unique design, it can even be used to take the temperature measurements of pipes that are up against walls or other surfaces. Because the clamp has a very strong spring, it will stay put in virtually any pipe orientation including vertical pipes.

The ATC1 is available immediately and priced at $49. Fieldpiece offers a wide variety of otherType-K thermocouples for field service technicians for measuring gases, surfaces, fluids and semi-solids.

Fieldpiece’s New K-Type Thermocouples Stay Right Where The Technician Wants Them To

Brea, Calif. — Fieldpiece Instruments has added two new thermocouples, ATA1 and ATWB1, to its extensive line of thermocouples for the HVAC/R field service technician. Designed to solve common problems encountered in the HVAC/R field service, these thermocouples have an alligator clip on the end so they stay put even when tugged on by the technician.

To do superheat, two temperatures are needed—outdoor dry bulb measuring the air stream in front of the condenser coils, and indoor wet bulb measuring the air stream at the return air register or in front of the evaporator coil. The ATA1 measures dry bulb and the ATAWB1 measures wet bulb. In both cases, Fieldpiece’s alligator clip design will hold the thermocouple in place so it can consistently measure the temperature of the air stream.

The new thermocouples work with any instrument that accepts a standard k-type plug, including the Fieldpiece SC66, SC67, SC76, ATH3, ST3, and LT17. The thermocouples come with the easy-to-store “wrap-tab” plug for lead storage. Just wrap the lead wire around the tab for convenient storage.

ATA1 Bead Thermocouple: the alligator clip holds the thermocouple firmly in place. Now the technician can be sure his thermocouple will stay in place.

ATWB1 Wet Bulb Thermocouple: technicians can measure wet bulb easily and accurately with the ATWB1. Just wet the “sock” with water, put it in an air flow, and measure wet bulb with any k-type thermometer. This also has an alligator clip to keep it in place.

“Fieldpiece designed these thermocouples after getting a lot of input from HVAC/R field service technicians. They may look simple, but they both solve real world problems better than anything else!” says Rey Harju of Fieldpiece.

The thermocouples are available immediately. Fieldpiece also offers a wide variety ofType-K thermocouples for field service technicians for measuring gases, surfaces, fluids and semi-solids.

HVAC/R Instruments Vital in Military Effort

from the article:

The Right Stuff for Use in the Field
by Jack Sine
June 28, 2010

“They’re a critical part of the work HVACR technicians do. Often called “tools of the trade,” the instruments and tools a technician has in his bag are almost as important to him as his expertise. A tech can possess all the knowledge and experience in the world, but if one of his tools fails or is inaccurate, it can really ruin his day and do damage to his employer’s business. In the case of Warren Brader and his crew, lives could literally hang in the balance…”

Fieldpiece test instruments are essential in keeping military communications up and running around the world.

How Manometers Help HVACR Professionals Diagnose and Balance Furnace and A/C Systems

What Is a Manometer?

A manometer is an instrument used to measure and indicate pressure. There are two types of manometers, analog and digital. The most basic and simplest form of an analog is the U-Tube manometer, a glass or rubber tube bent in the shape of a “U” where numbers are listed and spaced every inch on each side, and water is placed in between the bends of the “U”. When pressure is applied, either positively or negatively, the water moves to indicate the pressure behind it expressed in inches of water column (inWC). Inches of water column is the most common form of measurement in the HVAC industry when measuring static or gas pressure, although other units of measure are available and used worldwide. One of the most common analog types is the Magnehelic® gauge. These are found many times installed by the manufacturer of the system so that contractors can easily read the pressure of the system. However standalone digital manometers have become the new industry standard when it comes to measuring static pressure. With a higher accuracy readout, optional dual ports, additional parameters and readouts, in many cases they are much easier to use.

Why Should You Use a Manometer?

Static pressure is the amount of pressure a fan pushes or pulls against in order to move air throughout HVACs ducting. To imagine static pressure in a simple form, imagine the pressure in a tire, this is static pressure pushing against the inside of the tire to inflate it. One of the most overlooked opportunities for a service technician is to offer customers improved HVAC system performance. There are many ways to improve a systems performance – adding larger or additional ducts; finding and repairing pinch points and restrictions; installing dampers; balancing the system; and adjusting the fan’s speed.   A national study performed by NCI shows that the average inefficient HVAC system was performing at 55% of its rated capacity. That means that a customer is paying 45% more than they need to for the electricity to run their inefficient system.

Balancing static pressure is one of the most important factors in HVAC systems design. To put it simply, static pressure refers to the resistance to airflow in a HVAC system’s duct work and its components. The pressure (push) of the air must be greater than that of the resistance to the flow or air will not circulate properly or efficiently through the ducts.

If the static pressure exceeds the fans designed specifications the results will be a system with poor or low airflow. While simple maintenance, replacing restrictive air filters and cleaning dirty fans and coils, will increase airflow, if the static pressure in the system is over or under the designed conditions, the system will never operate at full efficiency or capacity. This can result in more unsatisfied customer call backs and the possibility of future equipment failure.

The Fieldpiece SDMN6 a trusted solution.

The SDMN6 also measures gas pressure up to +/- 60” WC (inWC) with a resolution of 0.1”, helping to determine if the gas pressure coming out of the house or regulator is correct. Static pressure readings up to +/- 2” WC with a resolution of 0.010” WC which will enable technicians to measure small differences in the static pressure. The instruments ability to read both positive and negative pressure allows for it to be used to measure vacuum control lines. The easytoread dual display shows the selected port on the upper display while the differential pressure is displayed below it, without the need to scroll through the display or make calculations. A zero button allows for a simple zero adjust bringing the meter to different ambient pressures. The included static pressure probes significantly improve the accuracy while allowing for an easier and simple setup.

With four different units of measurement to choose from (inWC, mmWC, mBar, and PSI), whatever measurement is required by the manufacturer can easily be selected and read. A brightly lit backlight display illuminates for ease of use no matter how dark the area you are working in. Additionally, the SDMN6 features an APO (auto power off) function to help conserve the life of the battery, a magnetic strap for “hands free” operation, and a carrying case that fits the manometer, all its accessories, and a few universal pressure switches. Backed by world class technical support and one of the industry’s best warranty services, you can rest assured you and your tools are in good hands.
