AMPROBE AMP-320 - 600 A AC/DC Clamp Meter Electrical Motor Maintenance

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 filters 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.

• True-RMS
• HVAC Features
  • Temperature measurement; User selectable °F or °C
  • DC Microamps for flame sensor testing
  • Capacitance measurement for start and run motor capacitors
• Amp-Tip Function
• Low Pass Filter for variable frequency drives
• Safety Rated: CAT III 600 V

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 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.
