Fieldpiece's top of the line True RMS Stick Meter, the Fieldpiece HS36 Expandable True RMS Stick Multimeter with Backlight includes the ranges you use everyday for HVAC/R field service plus includes a bright blue backlight and True RMS. Like the rest of the HS30 series, the Fieldpiece HS36 comes equipped with a magnetic hanger, along with detachable silicone test leads and alligator clip probe tips for remote and easy one-handed testing, as well as the full set of built-in safety features. The Fieldpiece HS36 auto-ranging stick meter also includes a bar graph on the LCD for an analog feel. Technicians who prefer Fieldpiece's expandable stick meters tell us this is the best digital multimeter for HVAC/R field Service.

The Fieldpiece HS36 works with all Fieldpiece accessory heads enabling the user to test a wider variety of parameters from a single meter. All this plus the removable tip test leads and alligator probe extensions make safe one-handed testing a snap with the Fieldpiece HS 36. True RMS allows the user to test true voltage and amperage on non-sinusoidal waveform lines such as those found on variable speed fan motors and more.


Auto Ranging Mode
The Fieldpiece HS36 Stick Multimeter is an auto ranging meter and is very accurate. For this reason, when you switch to a position on the meter that auto ranges, you’re likely to see movement on the display. For example, when the dial is turned to VAC, the Fieldpiece HS35 meter will drop to the millivolts range and you’ll see an “m” on the bottom of the LCD signifying a millivolt reading. The meter is picking up very low transient voltages in the air. Close the circuit by touching the leads together away from a voltage source. You’ll see the meter zero or a very small, stable millivolt reading.

Fieldpiece HS 35 Dial Settings/Ranges

Selecting Ranges
For DC voltage, set the Fieldpiece HS-36 Stick Multimeter to the VDC parameter instead of VAC. For all ranges choose a range just above the value you expect with the Fieldpiece HS-36. If display reads "OL" (overload), the user should select a higher range. However, if display shows less than three numbers, select a lower range for better resolution.

Features and Benefits

The Fieldpiece Series of HS meter is unlike any other found in HVAC/R. Fieldpiece naturally incorporates a number of safety features, both those you can and can’t see, into their meters. In addition, the Fieldpiece HS series accepts modular test instrument accessory heads. The Fieldpiece HS33 Manual Ranging Stick Multimeter is the first evolution of the stick meter concept. While the function of the Fieldpiece HS33 meter is similar to the original stick meter line, we’ve updated it since its introduction to include a number of features that make the HVAC/R technicians job easier, better and safer.

Non-contact Voltage
With the red NCV tab on the tip of the meter close to an AC voltage, press and hold the NCV button. The NCV LED will light and the beeper will beep. The closer you get to AC voltage, the louder the beep. The NCV function of the Fieldpiece HS 36 is sensitive enough to detect 24VAC on thermostats.

High Voltage and Continuity Indicators
In any VAC/VDC range, when the user touches a voltage greater than 30V, the beeper will beep and the red Hi-V LED will signal you. The continuity beeper and green LED tell the user if the circuit you’re testing is open or closed (using the switch position to the right of OFF).

Microamps DC - Flame rectififier diode test
The Fieldpiece HS35 can be used to measure the Microamps DC for when the flame diode goes out. The first test when you get the familiar "my furnace turns on but then turns off again" call.


The Fieldpiece HS-35 Stick Multi-meter can be used to test motor-start and motor-run capacitors. To use, Disconnect the capacitor from power first, then Short the terminals to discharge the capacitor. To ensure the most accurate reading, Disconnect any resistors that might be between the terminals of the capacitor.

MAX and Data HOLD
  • Press MAX to store highest reading on the display.
  • Press MAX again to return display to real-time reading.
  • Press HOLD to hold current data on the display.

Plug any K-type thermocouple directly into the meter to measure temperature on the Fieldpiece HS-36. Temperature measurement with the Fieldpiece HS35 will be accurate even in fast changing environments because of excellent temperature compensation. One thermocouple is included. No adapter is required to use the Expandable Manual and Auto Ranging Stick Multimeter.

Silicone Leads with Detachable Probe Tips
Because the wire insulation is silicone, the Fieldpiece ADLS2 Deluxe Silicone Test Leads leads will stay flexible in cold weather and will not melt if bumped by a soldering iron. When testing electrical circuits with two hands, there is a risk that a careless mistake may complete a circuit through your body and potentially cause death or injury. Detachable probes tips and the modular design of the Fieldpiece HS36 allows the user to plug V lead tip into the top of the meter, connect an alligator lead tip to COM and ground, and perform a one-hand test more easily than most any meter on the market.

It wasn't too long ago that the only multimeter you could buy was designed for lab use or an electrician’s meter. However, today HVAC/R technicians can buy the Fieldpiece series of meters with functions and features specifically designed for field use. The Fieldpiece HS-36 is more rugged, convenient, and safe to use in a variety of enviroments. Clips for one-handed testing and Loud BEEPERS and bright LEDS to warn of dangerous voltages, even in noisy environments. The Fieldpiece HS36's Manual Range and Automatic HOLD and MAX helps the user remain focused on the test point.

The features and benefits are the competitive advantages when it comes to the HS36. The Fieldpiece HS36 Expandable True RMS Stick Multimeter with Backlight is a manual ranging and auto ranging meter in one. Designed specifically for HVAC/R field service, the Fieldpiece HS36 is an affordable, flexible addition to any toolkit. Plus modular expandability allows the user to take a truckload of test instruments to the job in a bag over the shoulder.
