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

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.
