Pinza amperimétrica Amprobe 330 – TRMS Motor Maintenance Clamp Meter (1000 A AC/DC)

Amprobe 330 – TRMS Motor Maintenance Clamp Meter (1000 A AC/DC)

If you’re looking for a versatile clamp-on amp meter for electrical motor maintenance and HVAC testing in high voltage industrial environments, the AMP-330 Clamp Meter is the best clamp meter for the job. It is the best clamp meter in the AMP-300 Series line including all the features of the AMP-320 plus a work light, peak hold, CAT IV 600 V, CAT III 1000 V safety rating and large 2.0 inch (51 mm) jaw. HVAC technicians will find the temperature and capacitance measurements they need plus DC Microamps for testing flame sensors. It also had core motor testing capabilities such as motor rotation, 3-phase sequence testing, and inrush current measurement for motor start-up monitoring. The low pass filter allows you to accurately measure current and voltage on variable frequency drives. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, enabling accurate current measurement of both large and small diameter wires. It also offers a full range of standard multimeter features, including AC/DC current, AC/DC voltage, frequency, True-RMS, non-contact voltage detection, resistance, and continuity.

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 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.

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.
