Maintenance; Calibration - ABB CB-2000 User Manual

6. Maintenance

Only the specified replacement parts should be used for maintenance purposes.
The manufacturer will not be held responsible for any accident occurring following
any repairs made other than by its After Sales Service or an approved repair shop.
6.1 Maintenance
Regularly check the cables and potential leads, as well as their contacts.
The contact surfaces of the clip-on transformer must be kept clean to maintain accuracy. The surfaces
must be regularly checked, especially if the meter is used in polluted areas.
The clamp must be kept away from any conductor and disconnected from the measuring instrument.
Cleaning the clip-on transformer
1.
Clean the clamp's casing, arms and output cable with a sponge dampened with soapy water.
2.
Rinse these parts with a sponge dampened with clean water.
3.
Never run water over the clamp. Dry with a cloth or pulsed air (at a maximum temperature of 80°C).

6.2 Calibration

The meter is calibrated with the clip-on transformer when manufactured; see the included quality docu-
ment. To ensure that the meter is working properly and with optimal accuracy, calibration is recom-
mended once a year.
Any clip-on transformer other than the one specified on the back of the
CB-2000 should NOT be used. Usage with a non-specified clip-on trans-
former may result in inaccurate measurement readings.
