Features

Three Connector Jacks with Automatic Blocking Sockets (ABS)
All current ranges are implemented via a single connector jack which prevents any possibility of operator error. Auto-ranging is available in all current measuring ranges. Beyond this, the automatic blocking sockets prevent incorrect connection of the measurement cables, as well as selection of the wrong measured quantity. Danger to the user, the instrument and the device under test resulting from operator error is thus ruled out.

Measurement with Current Clamp Transformers and Sensors
Current clamp transformer and sensors are used for current measurements without interrupting the circuit under test, and for high amperages (> 16 A). The measured current value is automatically calculated and displayed for the user with the help of the adjustable clamp factor.

Activatable Filter for V AC Measurement
A 1 kHz low-pass filter can be activated if required, for example when measuring motor voltage at electronic frequency converters. The input signal is checked by a voltage comparator for dangerous voltages as long as the low-pass filter is activated. A highvoltage symbol appears at the display if dangerous voltage (> 45 V) is present.

Measurement with Current Clamp Transformers and Sensors
Current clamp transformer and sensors are used for current measurements without interrupting the circuit under test, and for high amperages (> 16 A). The measured current value is automatically calculated and displayed for the user with the help of the adjustable clamp factor.

Automatic Storage of Measured Values
The DATA function automatically saves the digitally displayed measured value after settling in. Acoustic signaling is also used to indicate whether the new measured value deviates from the initial reference value less or more than 0.1% of the measuring range.

Memory Mode Operation
The METRAHIT PM PRIME / METRAHIT ULTRA is equipped with a quartz-movement synchronized measurement data memory (2 MB), which has enough capacity for up to 300,000 measured values depending upon configuration. This allows for use of the instrument as an autonomous real-time data logger.

Measurement data recording is executed either:

  • Time-controlled with an adjustable storage interval ranging from 0.1 s to 9 hours
  • Dependent upon measured value in the event of exceeded limit/delta value
  • Automatically after the measured value settles in
  • As an individual measured value by pressing a key

Memory content can be read out from a PC with the help of the interfaces mentioned below, as well as analyzed and documented with METRAwin 10 evaluation software.

DAkkS Calibration Certificate
Each multimeter is individually adjusted, subjected to final inspection and calibrated. Adherence to the specification is confirmed by means of the included DAkkS calibration certificate, which is valid worldwide (recognized by EA and ILAC). After the specified calibration intervalhas elapsed (recommended interval: 1 to 3 years), the multimeters can be recalibrated at any time in our own DAkkS calibration laboratory.
