B Measurement tolerances
Accuracy indicated in ±(% related to the final range value + number
of digits = dgt(s) ) Accuracy is valid for 1 year at a temperature of
+23 °C ±5 K, at a rel. air humidity below 80 %, non-condensing.
Operational
mode, DC
voltage source to +199.9 mV
The supply impedance of the connected measuring device
should not go beyond 1 kohm..
DC current
source
Supply impedance up to 500 ohm in the range between 0 and
19.99 mA
Supply impedance up to 400 ohm in the range between 20 mA
and 24.0 mA
DC current
measurements 24.0 mA
DC current
source, two-
conductor-loop
Output voltage 12 VDC ±2 V in the loop; measurement of the loop
current
Caution!
Exceeding the maximum input ratings or a short-cir-
cuit of the source impedance can damage the cur-
rent calibrator.
