4. MEASUREMENT RANGE
A measurement range determines the measuring limits. The meter has several measurement ranges.
1) Select a proper measurement range:
If the selected measurement range is too small (the measurement signal exceeds the measurement range),
the meter will display “OL” on the LCD.
If the selected measurement range is t0o large, the measurement results may have a relatively low
resolution.
2) Auto range and Manual range
The meter has both auto range and manual range for the measurements.
In the AUTO measuring mode, “AUTO” appears on the display. The meter will automatically select a
most suitable range for the measurement signal.
In the MANUAL measuring mode, the measuring range is selected manually by pressing
RANGE
key.
If there is more than one range in a measuring function, the meter will default in AUTO range.
3) Enter or exit manual range mode
Press
RANGE
key to select manual range mode. Then, every press on the
RANGE
key, the meter
steps to a higher range and will return to the lowest range when the higher range is stepped into.
This allows users to override the auto range and lock the meter in a specific range.
In HOLD or MAX/MIN recording mode, changing the measurement range manually will automatically
exit the HOLD or MAX/MIN mode.
Press
RANGE
key for at least 2 seconds, the meter returns to AUTO range mode.
