7.4 Buzzer mode up to 2 kΩ (1 kΩ on analogue scale)
The buzzer is limited to 2 kΩ of measurement range. This is deliberate as it increases the buzzer response speed.
Without this limit the instrument would have to auto-range down from 999 kΩ on every test and dramatically slow
the response to low resistance measurements.
To enable the buzzer:
1. Press Hot key 4 to enable buzzer
Press Hot key 4 again to turn it off.
2. When the buzzer is on, it sounds when the circuit resistance
is less than a preset value. This is 0.5 Ω by default but can
be changed in settings; Refer to 15.6.1 Continuity buzzer
threshold (limit alaram) on page 83.
The preset value is displayed in the bottom of the display
as shown in the example right. Here the buzzer limit has
been set to 1 Ω.
