Megger MFT-X1 User Manual

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.
