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.

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 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 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 HOLD
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.
