Calibration certificate
A.1 Sample calibration certificates
Your meter was shipped with three calibration certificates. The calibration certificates
describe the calibrations and configurations that were performed or applied at the factory.
The calibration factors are provided on three calibration certificates:
• The first certificate provides the calibration factors in the CDM format, A
n
, in SI units.
These are obtained from factory calibration of your device.
• The second certificate provides the calibration factors in the legacy format, K
n
, in SI
units. These factors represent the current calibration factors converted to the
format used by the 7835 and 7845 meters.
• The third certificate provides the calibration factors in the legacy format, K
n
, in
imperial units. These factors represent the current calibration factors converted to
the format used by the 7835 and 7845 meters, and then converted to imperial units.
If you have existing programs that use the K factors, update your programs with the new K
values in the appropriate units. In all other situations, use the A-format calibration factors.
