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/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.

3.1.3 Battery Saver

The Meter enters the "sleep mode" and blanks the display if the Meter is on but not used for

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.

3.1.4 Relative measurement mode

The Meter will display relative measurement in all functions except frequency.
