Calibrateur multifonctions CX 1651
The energy value can be set in two ways:
Direct setting of energy
•
Select the energy mode and then keep pressing the center cursor button until [
appear under the time value (E = xxx.xxxx) supplemented with indication of the set mode.
•
The value can be set using numeric keyboard, cursor buttons or potentiometer and confirmed by pressing
Ws/kWs/MWs, VAs/kVAS/MVAs or VArs/kVArs/MVArs display buttons depending on the set mode. The
value can also be confirmed by pressing ENTER.
•
Time value is recalculated using new set energy.
Setting the time
•
Select the energy mode and then keep pressing the center cursor button until [
appear under the time value (t = xxx.x s).
•
The value can be set using numeric keyboard, cursor buttons or potentiometer and confirmed by pressing "s"
display button depending on the set mode. The value can also be confirmed by pressing ENTER.
•
Energy value is recalculated using new set time.
Grounding of the calibrator and the instrument to be calibrated in the P-E mode
When calibrating the power and energy meters with separate voltage and current circuits, it is advisable
to select GND U ON and GND I ON (both grounding methods on) on the CX 1651 calibrator. This
setting will ground both the current and voltage output of the calibrator.
If the instrument to be calibrated has electrically connected and not grounded current and voltage inputs,
GND U ON and GND I OFF should be selected on the CX 1651 calibrator.
If Lo and -I terminals on the calibrator are connected AND the same terminals are connected at the
instrument to be calibrated, resulting voltage drop at the current cables can damage the relay which
interconnects Lo and -I terminals with GND terminal in the calibrator.
