Voltage Simulator
The instrument includes the following simulator functions:
Direct voltage V DC, frequency f, resistance
Ω,
temperature
°
C (for resistance thermometers or thermocouples) and cur-
rent mA DC.
Voltages can be simulated within the following ranges:
0
…
±
300 mV, 0
…
3 V, 0
…
10 V and 0
…
15 V.
The resistance of the interconnected circuit should not be any
less than 1 k
Ω
.
➭
Connect the DUT with the measurement cables as
shown.
➭
Select the V calibration function with the rotary switch.
➭
Setting the voltage simulation value:
Press
$ !
keys to select the decade, i.e. the position of
the digit you wish to change, and press
#"
keys to set
the respective digit.
➭
Changing the voltage simulation value:
Press the
ESC
key until you proceed to the voltage range
sub-menu. Press
#"
keys to set the respective digit.
Press
↵
key to return to the main menu.

Pulse and Frequency Generator (positive square-wave
pulse)
Voltage and frequency can be generated independent of one
another with the frequency generator.
The output signal is a square wave. The resistance of the
interconnected circuit should not be any less than 1 k
Ω
.
➭
Select the
/Hz calibration function with the rotary
switch.
➭
Setting voltage amplitude (0
…
15 V):
Press the
ESC
key until you proceed to the menu for set-
ting voltage amplitude.
The decade (i.e. the position of the digit to be changed) is
selected with the
$ !
keys, and the respective digit is
set with the
#"
keys.
➭
Changing the voltage simulation range:
Press the
ESC
key until you proceed to the voltage range
sub-menu. Press
#"
keys to set the respective digit.
Press
↵
key to return to the main menu.
➭
Setting the frequency value (1
…
1000 Hz):
Press
↵
key until you proceed to the frequency main
menu. Press
$ !
keys to select the decade, i.e. the po-
sition of the digit you wish to change, and press
#"
keys to set the respective digit.
