AMP-300 Series

Motor Maintenance TRMS Clamp Meters

The Modern Evolution of the Professional Clamp Meter

Amprobe’s AMP-300 Series True-RMS Clamp Meters offer a complete range of measuring functions for modern industrial environments, motor testing and HVAC applications.

All models feature True-RMS sensing, low pass lters and fast response processors for

quick, error-free measurements. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, and a third input jack enables motor rotation and 3-phase sequence testing.

AMP-300 Series 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 lter).

• 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 lter 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 ame sensors. Test the proper operation of the ame 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.
