3.6.2 Threshold resistance level
You can define a threshold resistance from 1 Ω to 1000 Ω. Factory default value is 10 Ω. Follow the steps
below to define the resistance level:
1. Press for Continuity Measurement.
2. Press → to enter the submenu level, “1: CONTINUITY” will be displayed.
3. Press to enter the parameter level, the current LEVEL value will be displayed.
4. Use and keys to change the cursor position and use and keys to
increment or decrement the digits respectively. Enter a value from 1 to 1000.
5. Press (ENTER) to confirm your setting. Message “CHANGE SAVED” will be displayed for a
moment.
6. Press or → to exit the menu and return to the continuity measurement.
3.7 Testing Diode
The multimeter can also be used to measure the forward voltage drop of general-purpose diodes and
zener diodes. A current range (1 mA, 100 μA, or 10 μA) can be selected for diode measurement.
Note: Diode testing defaults to MED (1 PLC) rate and cannot be changed.
3.7.1 Connections
Assuming the multimeter is under factory default conditions, the basic procedure for diode testing is as
follows:
1. Connect test leads to INPUT HI and LO terminals.
2. Press → for diode measurement function.
3. Connect test leads to the diode under test as shown in Figure 3-6.
4. Take a reading from the display.
