4. Source
From the calibrator, you can source a DC voltage, DC current, SINK
current, resistance, thermocouple, RTD, frequency or pulse signal.
WARNING
●
To avoid electrical shock, do not apply any voltage above 30 V to the output
terminals. Always use the calibrator in locations with a voltage to ground
below 30 V.
CAUTION
• Do not apply any voltage to the output terminals for ranges other than 20 mA
SINK. Otherwise, the internal circuitry may be damaged.
• The instrument has been calibrated without taking into account a voltage
drop due to the resistance component of the lead cables for source. Care
must be taken therefore when drawing a load current since the voltage drop
due to the resistance component (approximately 0.1
Ω
on a round-trip basis)
of the lead cables serves as an error.
