If voltage over 100 V is set in the voltage mode, special algorithm must be followed to connect the output
terminals. The algorithm is described in the „Generation of calibrated voltage“chapter of this Manual.
18.6. S etting the frequency
Frequency can only be selected in AC voltage (ACU) mode, AC current (ACI) mode , power (P-E) mode and
frequency (f) mode. In each mode the frequency has a slightly different meaning and the frequency is therefore
set in a different manner.
18.7. AC voltage (ACU), AC current (ACI)
Set value of frequency is included in the “minor data” section of the display in ACU, ACI, P-E modes.
18.7.1. Frequency change
• First select the AC voltage or AC current mode by pressing U (I), AC buttons or selecting the P-E
mode using the display. Frequency value „f = xxx.xx Hz“ appears in the “minor data” section of the
display. “ f “ symbol is displayed above one of the display buttons.
• After “ f “ display button is pressed, [ _ _ _ _ _ _ _ ] symbols appear below the frequency value.
Numeric keyboard can be used to enter the desired value. Press “ Hz “ or “ kHz “ to confirm the
value. The value can be set using the buttons or the potentiometer.
If too large or too small value is entered, the calibrator displays the maximum (minimum) value which is allowed
for the selected function.
