Multimeter
The calibrator includes a built-in multimeter which can measure DC voltage, DC current and
frequency. Measured signal must be connected to the “METER INPUT” terminals. Terminals mA,
COM are for current measurements. Terminals V, COM are for voltage and frequency
measurements.

Function selection
Measurement funkction should be selected in Main menu (item Meter).
Press UP, DOWN display buttons or use the rotary knob to select one of the following
functions:
*
Voltage – DC voltage range 10V
*
Current – DC current range 20mA
*
Frequency – frequency range 10 kHz
Notes:
*
The multimeter can be used as a DC multimeter with ranges 10V and 20mA.
*
Frequency measurement is possible up to 15 kHz. Input signal must be within 0.2 to 5 V
range. Square wave or pulse shape of the input signal is expected.
The manufacturer does not recommend connection of multimeter inputs to
calibrator outputs.
Such connection can result in presence of high voltage at multimeter inputs,
which can damage the multimeter.
