MULTIMETER - FUNCTION SELECTION
The multimeter is active all the time and can be simultaneously used with the calibrator.
The upper part of the display shows the values and parameters of the Multimeter:
AUTO
Autoranging ± 2 ... ± 200VDC, settable with the key Auto.
FIX
Firm voltage ranges ± 2V, ± 20V, ± 200V DC, settable with Auto.
Firm current range ± 100mA DC, settable with 100mA.
With the key FN following mode of operation can be set:
INP
The display shows the input signal
HLD
HOLD the display
MAX
The display shows the maximum value
MIN
The display shows the minimum value
RST

SOFTWARE CALIBRATION
The voltage and the current ranges of the multimeter and the output signals of the calibrator can be
precisely calibrated by using the keyboard. The calibration menu can be opened with the key Set.
A full calibration of all 5 ranges or selected ranges only can be approached. A five digit multimeter
10VDC and 20mADC will be used as well as a Voltage/Current calibrator 100mA, 2V, 20V and 200VDC.
