Section Nine Calibration

Calibration: In order to keep the designed accuracy of this Instrument, it is recommendable to calibrate your

calibrator once a year. The following example shows the use of recommended standard equipment to perform the
calibration.
 Usage：Never apply more than the max. permitted voltage to the input of the calibrator, otherwise the overvoltage
will lead to possible damage to the input section.
 Usage: during the operation, avoid short circuit and never apply more than the max. permitted voltage to the output
of the Instrument or to a co-working standard device, otherwise any mal-operation will cause possible damage to their
internal circuits.
