3. 1 Calibration Interval
The DM3068 must be periodically calibrated; the calibration interval depends upon
the requirements of the measurement accuracy.
For the measurement needs higher accuracy, a 90-day interval is recommended and
less than 1 year interval is possible in most situation.
The accuracy will not be guaranteed until you perform a periodical calibration.
An interval higher than 1 year is not recommended under all circumstances.
3. 2 Calibration Notice
To ensure accuracy, the meter should be completely recalibrated when the interval is
reached whatever interval is chosen.
Even though the meter has passed the performance test, the specifications (see
“Specifications”) cannot be guaranteed unless recalibration is done.
3. 3 To Obtain Calibration Service
As the DM3068 does not support user calibration, please send your meter back to us
for professional calibration when necessary.
