ust Function
The zero adjustment function adjusts the zero position of the
resistance and voltage ranges of this unit.
The value read during zero adjustment is taken as zero, and
used to calibrate subsequent measurements.
1. Short the SOURCE and SENSE of the 9460 CLIP TYPE
LEAD WITH TEMPERATURE SENSOR together as shown in
the figure below.
2. Press the
0ADJ
key. During zero adjustment, "0Adj"is
displayed in the resistance measurement display position.
3. When "0Adj" disappears and measurement starts, connect the
leads to the battery to be tested.
Keep the leads shorted together throughout the zero adjustment
process.
The zero adjustment is valid for the currently selected range
only, as long as the power remains on. Powering on the unit
resets all zero adjustment values.
When the resistance or voltage value is displayed as "----", or
whenthereadingismorethan"200", "FAIL" is displayed. The
zero adjustment is not carried out.
