Minimum Input Span
The minimum input span is the minimum difference between input 1 and input 2
signals required to complete the calibration or scaling of the meter. The minimum
span is 0.10 mA.
If the minimum span is not maintained, the meter reverts to input 2, allowing the
appropriate input signals to be applied.
Re-Calibrating the Internal Calibration Reference (ICaL)
The Internal Calibration (ICAL) menu, located in the Advanced features menu, is
used to recalibrate the internal calibration reference. Recalibration is recommended
at least every twelve months. Refer to Internal Calibration (ICAL), page 42 for
instructions.
Setting the Time Base (t.base)
The meter calculates total based on rate and a time base of units per second, minute,
hour, or day.
Press the Enter button, at any time, to accept a setting or Menu button to exit without
saving changes.
