I2 calibration
1. Connect external calibrated RMS A-meter (10A, accuracy better than 1%) in series with the load circuit. Use at least 10% load of the CCR
capacity.
Warning!
High voltage circuit – De-energize CCR before connecting!
Note : For more information on easy meter connection, see
in Appendix M – Ouput Terminals. Clamp meter
accuracy is normally not adequate for 1% accuracy. For periodic maintenance checks, clamp type meter is still recommended for safety reasons.
1. Select the second highest current step (approx. 5A).
1. Go to I2/U2 calibration: select Set/Cal/Out.
1. Adjust the I2 reading on datafield 1 to equal with the external meter reading.
1. Make sure that the readings are equal then select Set.
Warning!
Make sure that there is max 10% deviation between the two readings. Selecting set
with bigger difference between the readings may result to over current on the output
circuit!
1. Check that both readings are equal, if necessary repeat steps 4-6.
Note : I2 calibration affects also to VA-drop function.
Calibration with short circuit load (U2 = 0) is not allowed.
Calibration of more than ±10% from factory defaults is not allowed -> ERR indication in display.
U2 calibration
1. Connect external calibrated RMS V-meter (Min 30V, accuracy better than 1%) to the voltage transformer test
outputs located on the right side of the power unit of the control rack.
1. Select the maximum current step (6.6A).
1. Go to I2/U2 calibration: select Set/Cal/Out and then Next.
1. Check the external meter reading and adjust the U2 reading on data 1 to be equal with the external meter reading and then select Set .
Note : Round up to next bigger value e.g. 20.12->20.2.
1. Make sure that the both readings are equal and if necessary repeat step 4.
Note : U2 calibration affects also to VA-drop function
Calibration of more than ±10% from factory defaults is not allowed -> ERR indication in display.
