How to Use a Fieldpiece Multimeter

Fieldpiece meters address the specifications and parameters required for most HVACR applications. You can measure current, resistance, voltage, capacitance, frequency, continuity, and even temperature.

In general, here’s how to use a fieldpiece multimeter:

  • Insert the test leads to the black “COM” and red “+” jacks for electrical testing. Adjust the dial to the appropriate measurement.
  • Attach probes to the test points and read the results.
  • You should disconnect the test leads for temperature testing, shift the TEMP switch to the right, and attach the temperature probes or Type K thermocouples.

There are still a lot more capabilities to your fieldpiece HVAC multimeter, especially if you learn and master how to use its many features.

Read along as I walk with you through our detailed guide about how to use a fieldpiece multimeter and its features:

How to Use Fieldpiece Meters in 5 Ways

You may use fieldpiece instruments to measure multiple factors and metrics for most HVACR operations. Continue reading to learn how to measure current, resistance, voltage, capacitance, frequency, continuity, and even temperature using fieldpiece instruments:

1. Through Electrical Testing

  1. Attach the test leads to the jacks. You should connect the black probe to the “COM” jack and the red probe to the “+” jack.
  2. Set the dial to VDC mode to test DC voltages on circuit boards. (1)
  3. Point and touch the probes to the test terminals.
  4. Read the measurements.

2. Using a Fieldpiece Multimeter to Measure Temperature

  1. Unplug the leads and move the TEMP switch to the right.
  2. Insert the Type K thermocouple directly into the rectangle holes.
  3. Touch the tip of the temperature probes (Type K thermocouple) directly into the test objects. 
  4. Read the results.

The meter’s cold junction enables exceptionally precise measurements even when the ambient temperature quickly fluctuates.

3. Using Non-contact Voltage (NCV)

You can check 24VAC from a thermostat or live voltage up to 600VAC with the NCV. Before use, always test a known live source. A segment graph will show the existence of voltage and a RED LED. As the intensity of the field increases, the loud beep changes from intermittent to constant.

4. Performing a Continuity Test Using a Fieldpiece Multimeter

The fieldpiece HVAC multimeter is also a perfect tool to check for continuity. Here is how you can do so:

  • Power off the fuse. You only need to pull down the lever to switch the power off.
  • Take your fieldpiece multimeter and set it to continuity mode.
  • Touch the multimeter’s probes to each tip of the fuse.
  • If your fuse does not have continuity, it will make a beeping sound. Whereas, if continuity is present in your fuse, the digital multimeter will refuse to beep.

5: Testing Voltage Differences Using a Fieldpiece Multimeter

Voltage differences can be dangerous. Thus, it’s worthwhile to check your fuse and see if there is one. Now, get your fieldpiece multimeter and follow the instructions below:

  • Power on your fuse; make sure it is live.
  • Get your fieldpiece multimeter and set it to voltmeter mode (VDC).
  • Put the multimeter’s probes to each end of the fuse.
  • Read the results. It will show zero volts if there is no voltage difference present in your fuse.

FAQs

What are the features of a fieldpiece multimeter?

– When measuring voltages greater than 16VAC/35VDC, you will notice a bright LED and a beeper sound an alarm. It’s a warning for excessive voltage.

– Set the clamping claw to NCV (non-contact voltage) and point it at the likely voltage source. To see if the source is “hot,” keep an eye on the bright RED LED and the beeper.

– The thermocouple will not plug after a while measuring voltage because of the temperature switch.

– It includes a power-saving feature called APO (auto power off). After 30 minutes of inactivity, it will automatically switch off your meter. It is already on by default, and APO will also appear on the screen.

What do the LED lights indicate?

High Voltage LED – You can find it on the left side, and it will make a beeping sound and glow when you are testing high voltage. (2)

Continuity LED – You can find it on the right side, and it will make a beeping sound and glow when you are testing for continuity.

Non-contact Voltage LED – You can find it in the middle, and it will make a beeping sound and glow when you are using the non-contact voltage feature of the fieldpiece meter.

What are the things to consider when using a fieldpiece multimeter?

Here are a few things to consider when using a fieldpiece multimeter:

– While taking measurements, avoid touching exposed metal pipes, outlets, fixtures, and other items.

– Before you open the casing, disconnect the test leads.

– Check the test leads for insulation damage or exposed wire. If there is one; replace it.

– Keep your fingertips behind the finger protections on the probes when taking measurements.

– When possible, perform one-handed testing. High voltage transients can permanently harm the meter.

– Never use fieldpiece multimeters during a storm.

– Do not pass the clamp’s rated 400AAC when measuring high-frequency AC current. The RMS clamp meter may become unbearably hot if you don’t adhere to instructions.

– Turn the dial to the OFF setting, unplug the test leads, and unscrew the battery cover when replacing the battery.

This gives me a unique ability to really be able to tell you what the best tools and recommendations are. I’m not only a carpenter but I also like machinery and anything to do with electrics. One of my career paths starting off was as an apprentice electrician so I also have a lot of experience with electrical products and anything related.
