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.
