Pressing the Power key once when the power is off turns on the calibrator.
Pressing the Power key for 2 seconds turns off the calibrator.
Turning On/Off the Backlight
The LCD can be backlight. Pressing the key turns on the backlight, while pressing the key once again turns it
off. This feature makes it easier for you to view the LCD when operating the calibrator in dark places or when
carrying out source or measurement. Battery life shortens when the calibrator is operated on batteries.
Note
The backlight automatically turns off after 10 seconds. Press the key once more to relight it.
The time could be reset in the factory default parts, see Chapter 8 "Factory Default".
7 Source
From the calibrator, you can source a DC voltage, DC current, simulate transmitter, resistance, thermocouple,
RTD, frequency, pulse signal or contact output.
Warning
To avoid electrical shock, do not apply more than the rated voltage, as marked on the calibrator, between
terminals or between any terminal and earth ground. Always use the calibrator in locations with a voltage to
ground below 30 Vp-p.
Caution
Do not apply any voltage to the output terminals for ranges other than 4-20mA simulating transmitter
output, Otherwise, the internal circuitry may be damaged.
The instrument has been calibrated without taking into account a voltage drop due to the resistance
