Section Nine Calibration
Note
• Calibration : In order to keep the designed accuracy of this
Instrument. it is recommendable to calibrate your calibrator once a
year. The following example show 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 over voltage 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.
