Generation of electric power
The calibrator can generate exact value of electric power and energy. Power function modes
provides output voltage at VOLTAGE OUTPUT HI – LO terminals and output current at
CURRENT OUTPUT HI – LO terminals. Depending on the setting of the calibrator, voltage up to
600 Vef can be present at the terminals.
Power setting range:
0.005 VA to 18 kVA (each channel)
Voltage setting range:
1 to 600 Vac, 1 to 280 Vdc
Current setting range:
5 mA to 30 A
Power factor setting range:
-1 to +1 (phase 0 to +359.99 °)
Frequency setting range:
DC, 15 Hz to 1 kHz
Control in the power mode
Press “P” button on the calibrator and then select AC or DC mode by pressing „AC“ or „DC”
button. The display shows the following data:
* main value of set power in selected unit of measurement VA, W, VAr
* voltage at VOLTAGE OUTPUT HI-LO terminals
* current through CURRENT OUTPUT HI-LO terminals
* power factor or the phase shift between the voltage and current in °.
* frequency, if AC power is selected
* uncertainty of set power
Set desired value of power using numeric keyboard, potentiometer or cursor buttons. Output
power is not yet connected to the output terminals.
Connect the instrument to be calibrated to VOLTAGE OUTPUT HI-LO and CURRENT
OUTPUT HI-LO terminals or short the CURRENT OUTPUT HI-LO terminals.
Press OUTPUT button.
Green LED is lit above the “On” button to indicate the connection of simulated electrical
power to the output terminals. Connected terminals are also displayed in the „Outputs state“
window as green circles.
Desired power is connected to output terminals.
