Comparator (99 sets)
The comparator function compares the measured values with preset High and Low limit values for
internal resistance and voltage level, and determines the range that the measurement should fall
into. Then, according to the following conditions, switches ON the corresponding LED, and sounds
an audible alert as shown in the table below for the WARNING and FAIL conditions.
Comparator Settings
1. Press and hold the SET button for 2 seconds, the display will show COMP.SET indicating the
comparator mode is enabled.
2. Use the or button to change the comparator number from 01 up to 99.
3. Use the V-RANGE or Ω-RANGE button to set the desired voltage and resistance measurement
range.
4. Press once, the LOW icon and the left two digits of the low limit resistance
will be flashing.
(Use the & buttons to select the desired value.)
5. Press once, the right two digits of the low limit resistance
will be flashing. (Use the
and buttons to select the desired value.)
6. Press once, the HIGH icon and the left two digits of the high limit resistance
will be flashing.
(Use the and buttons to select the desired value.)
7. Press once, the right two digits of the high limit resistance
will be flashing. (Use
the and buttons to select the desired value.)
8. Press once, the left two digits of the threshold voltage
will be flashing. (Use the
and buttons to select the desired value.)
9. Press once, the right two digits of the threshold voltage
will be flashing. (Use the
and buttons to select the desired value.)
10. Repeat step 2 to step 9 to set the next comparator number.
11. Press SET again to exit the comparator setting mode.
