Zero Adjust (REL)
The zero adjustment function is to zero the range of impedance and voltage.
The reading during zero adjustment will be taken as zero and will be used to
calibrate subsequent measurements.
1. Short the red and black test leads probe 4 terminals.
2. Press REL key. The display shows
value is zero, connect the test leads probe to the battery to be tested.
3. The zero adjustment is valid only for the currently selected range, as
long as the power remains on.
Using Comparator function (99 sets)
The comparator function compares the measured values with preset High and
Low limit values for internal impedance and voltage level, and determines the
range that the measurement should fall into. Then according to the following
conditions to light the corresponding LED, and sounds a beeper under the
WARNING and FAIL cases.
Comparator Settings
1. Press and hold down the "SET" key for 2 seconds, the display will show
COMP.SET to enter the comparator setting mode
2. Use the q or p key to change the comparator number, from 01 up to 99.
3. Use the V-RANGE or Ω-RANGE key to the battery voltage and impedance
to be measured range.
4. Press u key one time, the low limit impedance of the "two higher
digits" will be flashing. (Use the p & q keys to select the desired value.)
5.Press u key one time, the low limit impedance of the "two lower digits"
will be flashing. (Use the p & q keys to select the desired value.)
, then the impedance and voltage
