Functions
1
• Measurement
Independent of the source function, the calibrator measures DC volt-
age, AC voltage, DC current and resistance signals, a temperature sig-
nal based on a thermocouple (TC) or RTD, as well as frequency and
the number of pulses.
Function
Description
DC voltage
Measures a DC voltage signal in the 100 mV, 1 V, 10 V or
100 V range.
AC voltage
Measures a DC voltage signal in the 1 V, 10 V, 100 V or 300
V range.
DC current
Measures a DC current signal in the 20 mA or 100 mA
range.
The current terminals are equipped with a built-in
overrange input protection fuse.
Resistance
Measures a resistance signal in the 400
Ω
range.
Thermocouple (TC)
Measures temperature according to the type of thermo-
couple – K, E, J, T, R, B, S, N, L or U.*
1
(CA71 only)
RTD
Measures temperature according to the type of RTD –
Pt100 or JPt100. *
2
(CA71 only)
Frequency and pulse
Measures frequency in the 100 Hz, 1 kHz or 10 kHz range.
For pulse signals, this function measures the number of
pulses as a CPM (count per minute) or CPH (count per
hour) reading.
You can also select and configure the following functions.
Function
Description
Divided output function(
n/m)
Sources a “setpoint
×
(
n/m)” output signal, where the vari-
ables
m and n are defined as m = 1 to 19 and n = 0 to m.
Memory
Stores up to 50 sourced and measured values as a set.
Sweep
Changes the output signal in a linear manner.
Auto step
Automatically changes the value of
n in a setpoint
×
n/m
output in a step-by-step manner.
