DATA HOLD mode
Data Hold mode makes the meter stop updating the display. Enabling Data Hold function in
autorange mode makes the meter switch to Manual ranging mode, but the full-scale range remains
the same. Data Hold function can be cancelled by changing the measurement mode,
pressing RANGE key, or push HOLD key again.
To enter and exit the Data Hold mode:
1)
Press HOLD key (short press). Fixes the display on the current value, HOLD is displayed.
2)
A second short press returns the meter to normal mode.
3)
Pressing HOLD key and last for 2 seconds, the HOLD symbol in LCD will be blinking and the meter
will delay for 6 seconds, that enters HOLD mode.
3.1.3.
Manual ranging and Auto range mode
The Meter has both manual ranging and auto range options.
*
In the auto range mode, the Meter selects the best range for the input detected. This allows you
to switch test points without having to reset the range.
*
In the manual ranging mode, you select the range. This allows you to override auto range and lock
the meter in a specific range.
*
The Meter defaults to the auto range mode in measurement functions that have more than one
range. When the Meter is in the auto range mode, AUTO is display.
To enter and exit the manual range mode:
1)
Press RANGE key. The Meter enters the manual ranging mode. AUTO turns off. Each presses of
RANGE key increments the range. When the highest range is reached, the Meter wraps to the lowest
range.
Note: If you manually change the measurement range after entering the Data Hold modes,
the Meter exits this mode.
2)
To exit the manual ranging mode, press and hold down RANGE key for two seconds. The Meter
returns to the auto range mode and AUTO is displayed.
