What is It?

Solve those “no heat” calls fast and efficiently with the Fieldpiece Milliamps & Microamp Accessory, model AUA2. The head converts microamps (for flame rectifier diode) and milliamps (for heat anticipators and control circuits) to a mV signal for direct current reading on any meter with mV ranges. For resolution of 0.1 micro/milliamps, use a meter that displays 0.1mV. The AUA2 includes quick connect and mini-plug adapters to convert your "stick" meter, DL3 data logger, and EHDL1 electronic handle to a one-piece flame rectifier diode tester and heat anticipator checker.

 

How Does it Work?

The AUA2 accessory converts microamps and milliamps to a mV signal for direct current reading on any meter with mV ranges. Use it for flame rectifier diode tests, heat anticipator and control circuit checks.

OperationAUA2-flame-diode
  1. Connect the AUA2 to meter’s COM and VOLTS plugs. Connect through leads or slide head onto meter.
  2. Break flame rectifier diode circuit and connect AUA2 in series using the appropriate adapter. You can also use industry standard leads.
  3. Select microamps (for flame rectifier diode) or milliamps on the front of AUA2.
  4. Set the meter to mV AC or DC range to directly read micro/milliamps.

 

Features and Benefits

Measures milliamps and microamps for flame diode test. Measures 4 to 20mA control circuits.
  • Includes flame diode adapter kit (AQK3).
  • Resolution: 0.1 for meters with 0.1mVDC.
  • Accuracy: DC: ±(1.0%rdg + 1dgt) AC: ±(1.5% + 2dgts).
  • Max current: 200mA AC or DC.

 

Competitive Advantages

Like all of the Accessory Head model instruments that Fieldpiece designs, the AUA2 gives you the ability to do more work from one small bag of tools.  It is the only modular current instrument of its kind and provides you with valuable data in diagnosing “no heat” calls in the field when used with our meters, data logger and electronic handle.

HS33-SRC-product-tmb

Expandable Manual Ranging Stick Multimeter for HVAC/R - HS33

Based on the success of our original stick meter line, the HS33 was designed to measure even more HVAC/R parameters including temperature with quick compensation via a k-type thermocouple plug, a diode test and a built-in non-contact voltage (NCV) tester. The updated ergonomic shape fits firmly and naturally in your hand while testing. A magnetic hanger, along with the detachable test leads and alligator clip probe tips, allow you to remote test and perform other tests hands-free.  This is the stick meter schools prefer for their HVAC/R students. It’s got all the basics and more. VAC, VDC, AAC, ADC, temperature, capacitance (MFD) and a host of other built-in safety features.
