Product Detail

The AMP-320 embodies all the utilities needed to measure HVAC, general electrical or motor testing application. The clamp meter allows technicians to find the temperature and capacitance measurements needed, as well as DC Microamps for testing flame sensors. The unit boasts a motor rotation, inrush current measurement for motor start-up monitoring, and 3-phase sequence testing. Likewise, the Amp-Tip function provides meticulous measurement of current down to the tenth of an Amp. This enables precise current measurement of both large and small diameter wires.

Applications

Accurate measurement of current, voltage and frequency on all electrical systems including distorted, non-sinusoidal signals (True-RMS function) and variable frequency drives (low-pass filter).

Capacitance measurement for start and run motor capacitors.

Resistance and continuity functions to verify quality of electrical connections and to check if motor and transformer coils are working properly.

3-phase Motor and Phase Rotation Tests allow proper connection of a motor to a 3-phase system. Improperly connected motors will spin in a reverse direction, which may destroy the motor or equipment connected to it.

Low pass filter allows measurement of current and voltage on variable frequency drives (motors with speed controlled by frequency). Without this feature, the meter would provide erroneous readings when measuring voltage and current.

DC Microamps output for measurement of flame sensors. Test the proper operation of the flame sensor safety system in gas appliances. A broken sensor in a gas appliance will prevent the safety valve from opening and the appliance will not work.

Inrush current measurement for motor start-up monitoring, allowing users to verify that the motor is receiving the required inrush current to support proper motor start.
