- Auto-range current measurement from 1 A to 10 A (16A) via a single connector jack and a single fuse
|
Applications
The multimeter is suitable fo r universal use in electrical engineering, electrical installation, laboratory applications, telecommunication, training etc. The instrument can be used in the field and is equipped with internal, mains-independent supply power
Features
Three Connector Jacks with Automatic Blocking Sockets (ABS) 1) All current ranges are implemented via a single connector jack which prevents any possibility of operator error. 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 de vice under test resulting from operator error is thus ruled out.
1) Patented (patent no. EP 1801 598 , US 7,439,725)
Overload Protection
The instrument is safeguarded for up to 1000 V in all measuring functions by overload protection. Voltages of greater than 1000 V and current of greater than 10 or 16 A are indicated acoustically. Dangerous contact voltages are indicated when the 1 kHz low-pass filter is activated. The FUSE display appears at METRA HIT, X-TRA, METRAHIT OUTDOOR, METRA HIT TECH and METRA HITPRO instruments in order to indicate that the fuse for the current measuring input has blown.
RMS Value with Distorted Waveshape
The utilized measuring method allows for waveshape independent RMS measurement (TRMS AC and AC+DC) for voltage and current (METRA HIT, X-TRA, OUTDOOR up to 20 kHz).
Measuring 5 V Square-Wave Signals with the METRAHIT, X-TRA, OUTDOOR
This function makes it possible to test circuits and transmission cables by measuring the frequency and the duty cycle of pulses with amplitudes of 2 to 5 V and frequencies of 100 Hz to 1 MHz.
Analog Scale for Quick Trend Display – Bar Graph or Pointer
The analog scale (with additional negative range for zero frequency quantities) allows for faster recognition of measured value fluctuation than is possible with a digital display. The instrument can be switched back and forth between bar graph and pointer display.
