3.1 General Functions
3.1.1 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/LIGHT
key again.
To enter and exit the Data Hold mode:
1)
Press
HOLD/LIGHT
key (short press). Fixes the display on the current value,
H
is displayed.
2)
A second short press returns the meter to normal mode.
3.1.2 Manual ranging and Autorange mode
The Meter has both manual ranging and autorange options.
•
In the autorange 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 autorange and lock
the meter in a specific range.
•
The Meter defaults to the autorange mode in measurement functions that have more than one
range. When the Meter is in the autorange mode,
AUTO
is displayed.
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.
2)
NOTE: If you manually change the measurement range after entering the Data Hold modes,
the Meter exits this mode.
3)
To exit the manual ranging mode, press and hold down
RANGE
key for two seconds. The Meter
returns to the autorange mode and
AUTO
is displayed.

30 minutes.
Press the
HOLD /LIGHT
key or rotate the rotary switch to wake the meter up.
To disable the Sleep mode, hold down the SELECT key while turning the meter on.
