Enabling and Disabling the Change Alert™ Function

Press to enable an audible alert signal. The test tool draws your attention with a beep when the measurement changes more than 100 digits. In Ω mode the alert warns you when the measurement falls to less than 5% of the measurement range.

Changing the Refresh Rate of the Display

Select (FAST) to speed up the refresh rate in the measurement result display. A fast refresh rate is useful when you are making adjustments and must see the resulting reading as quickly as possible.

Select (SMOOTH) to average readings over the last measurements (8 seconds at 5 ms/div). It reduces the influence of noise or unstable input signals.

Select (no highlight) to get the normal readings.
