Select the insulation resistance tab from the settings page.
15.6.1 Continuity buzzer threshold (limit alaram)
The optional buzzer mode in continuity testing has a trigger resistance above which the buzzer will not sound. This
allows for quick testing when only audible confirmation the circuit resistance is below a given threshold is required,
rather than an absolute value. This threshold is called a limit alarm.
1. Select the continuity tab RLO from the General settings page using the right arrow (Hot key 5).
2. Press the green check button (Hot key 3).
3. Turn the right-hand rotary knob to choose the continuity buzzer limit alarm threshold.
The choices are:
0.3 Ω
0.5 Ω
1 Ω
2 Ω
3 Ω
4 Ω
5 Ω
10 Ω
20 Ω
30 Ω
40 Ω
50 Ω
100 Ω
200 Ω
4. When you have made your selection either press Hot key 3 to confirm it or wait three seconds for automatic
confirmation.
5. When you have made your selection either press Hot key 3 to confirm it or wait three seconds for automatic
acceptance.
15.7 Insulation resistance settings
1. Select the insulation RISO tab from the General settings page using the right arrow (Hot key 5).
2. Turn the right-hand knob to highlight the setting you want to change.
The options are:
Buzzer threshold
Live voltage limit
Lock button available
Timed test duration
Variable voltage
3. Press Hot key 3 to confirm your selection.
15.7.1 Live voltage limit
When you are performing an insulation test, if the instrument detects a voltage on the circuit you are testing, that is
greater than the live voltage limit you have set, it will give an audible and visual warning you and inhibit the test.
1. Select the live voltage limit option using the right rotary knob.
2. Turn the right-hand rotary knob to select the live voltage limit you want.
The choices are:
30 V
50 V
75 V
3. When you have made your selection either press Hot key 3 to confirm it or wait three seconds for automatic
confirmation.
