Gossen MetraWatt METRAHit 28C light - 3 Voltage Simulator; 4 Pulse and Frequency Generator (Positive Square-Wave Pulse)

6 GOSSEN METRAWATT GMBH
3 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 kΩ.
➭ 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.
4 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 kΩ.
➭ 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.
