Expandable Manual Ranging Stick Multimeter for HVAC/R - HS33

The Expandable Manual Ranging Stick Multimeter for HVAC/R, model HS33, was designed to include more features and ranges than our original slim line stick meters.










What is It?

Expandable Manual Ranging Stick Multimeter for HVAC/R with Temp, NCV, Diode Test and more - model 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. The rugged rubberized bumpers help this meter stand up to tough conditions in the field. Ranges include VAC, VDC, AAC, ADC, temperature, capacitance (MFD) and a host of other built-in safety features.


How Does it Work?

The HS33 is unique in that it’s a great “starter” meter for new field technicians as well as a top performer for veterans who prefer manual ranging digital multimeters meters. All Fieldpiece accessory heads slide on the top, enabling the user to test a wider variety of parameters from a single meter. All this plus the removable tip test leads make safe one-handed testing a snap.  As with all electrical testing, please read the Operator’s Manual and associated safety practices thoroughly before testing and adhere to industry best practices for safety when testing any current carrying device.

Selecting Ranges
For DC voltage, set the meter to the VDC parameter instead of VAC (shown below). For all ranges choose a range just above the value you expect. If display reads “OL” (overload), select a higher range. If display shows less than three numbers, select a lower range for better resolution. 









Connecting to Fieldpiece Accessory Heads



               1                                      2

Connect to Fieldpiece accessory heads by simply attaching them to the top of meter (1) or attach remotely through leads (2). For most heads, move dial to mVDC range shown (1). For the AAC clamp (ACH4), move dial to VAC range (2).

Disconnect test leads from voltage before plugging in thermocouple!
Insure the temperature being measured is stable. Maintain good contact between the thermocouple and what's being measured.
The velcro strip supplied is intended to be used as shown on the right. Tie thermocouple like this and wrap Velcro around surface to make sure bare wires are in close contact with surface being measured. This is especially helpful when taking pipe temps.
The k-type thermocouple supplied is designed with a “wrap tab” to keep the wire out of the way when not needed. Just wrap the wire around tab and pull through the hole at the top to keep in place as shown to the left. No more clutter when stored.


Features and Benefits

The HS meter series is unlike any other found in HVAC/R. We incorporate a number of safety features, both those you can and can’t see, into our meters.  In addition, the HS series accepts modular test instrument accessory heads. The HS33 is the first evolution of the stick meter concept. While the function of the meter is similar to the orgonal 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 VoltageHs33-with-probe-tip
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 with an analog feel and the beeper will beep. The closer you get to AC voltage, the louder the beep. The NCV function is sensitive enough to detect 24VAC on thermostats.  

The non-contact voltage feature can be used in conjunction with one probe tip to find which wire is live. With meter set to OFF, place probe tip in red plug as shown below. Hold down NCV while touching each wire, a noticeably louder buzz will sound when you’ve touched a live wire.


Using the included amp clamp accessory, model ACH4, on the 200 mVAC range allows you to read 0-400 amps directly on your meter with 0.1 resolution. Use it with the detachable test leads to remote the amp clamp and test with the blower door closed for more accurate readings.   

For motor-start and motor-run capacitors. Disconnect the capacitor from power first. Short the terminals to discharge the capacitor. Disconnect any resistors that might be between the terminals of the capacitor.

High Voltage and Continuity Indicators
In any VAC/VDC range, when you touch a voltage greater than 30V, the beeper will beep and the red Hi-V LED will signal you. BE CAREFUL! The continuity beeper and green LED tell you if the circuit you’re testing is open or closed.

MIN / MAX and Data HOLDHS33-volt-with-ASA1B
Press MIN/MAX once to begin recording MIN and MAX.
Press MIN/MAX to select current reading’s MIN or MAX.
Hold down for 2 seconds to exit MIN/MAX function. Press HOLD to hold data.

Silicone Leads with Detachable Probe Tips
Because the wire insulation is silicone the 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 HS33 allow you 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.

And More:

  • Rugged ABS case with rubberized bumpers.
  • Built-in magnetic hanger allows you to test with one hand or no-hands.
  • Built-in lead storage.
  • Ergonomic shape fits naturally in your hand.
  • Auto power-off (APO) to conserve battery life.


Competitive Advantages

The features and benefits are the competitive advantages when it comes to the HS33.  This is truly an HVAC/R multimeter.

It wasn’t too long ago that the only multimeter you could buy was designed for lab use. Today’s HVAC/R technician can buy meters with functions and features specifically designed for field use. And, they’re more rugged, convenient, and safe. Clips for one-handed testing. Loud BEEPERS and bright LEDS to warn of dangerous voltages, even in noisy environments. Magnetic hangers. Automatic HOLD and MAX so eyes stay focused on the test point. Silicone leads. Manual ranging.

Plus modular expandability allows you to take a truckload of test instruments to the job in a bag over your shoulder.

Field °F calibration
For accuracies of ±°F, calibrate the HS33 to a known temperature. A glass of stabilized ice water is very close to 32°F (0°C) and is usually very convenient but any known temperature can be used.

  1. Select the 200°F range.
  2. Remove back case and hold the battery in place with a rubber band so terminals are touching.
  3. Stabilize a large cup of ice water.
  4. Immerse the thermocouple probe and let it stabilize.
  5. Adjust VR3 (below battery) to get close to 32°F (0°C) then adjust VR1 (right of battery) to get within 0.1°F (0.1°C) of 32.0°F (0.0°C).
  6. To calibrate in °C, close the jumper that is just below VR1.
