3. FUNCTION DESCRIPTION
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 key again.
To enter and exit the Data Hold mode:
1. Press
HOLD key (short press). Fixes the display on
the current value, DATA-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.
