1. Functions
• Measurement
Independent of the source function, the calibrator measures
DC voltage, AC voltage, DC current and resistance signals,
a temperature signal 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
thermocouple – 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 variables
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.
