ENGLISH
To enter and exit the Data Hold mode:
1. Press
HOLD
2. A second short press returns the meter to normal mode.

3.1.2 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 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.
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.

3.1.3 Battery Saver

3.1.4 Relative measurement mode

The Meter will display relative measurement in all functions except frequency.
To enter and exit the relative measurement mode:
1. With the Meter in the desired function, touch the test leads to the circuit on which you want future
measurement to be based.
2. Press REL r key to store the measured value and activate the relative measurement mode. The
difference between the reference value and subsequent reading is displayed.
3. Press REL r key again return the Meter to normal operation.

Measurement Functions

3.2.1 AC and DC Voltage measurement

To avoid electrical shock and/or damage to the instrument, do not attempt to take
any voltage measurement that might exceeds 1000Vdc or 1000Vac rms.
To avoid electrical shock and/or damage to the instrument, do not apply more than
1000Vdc or 1000Vac rms between the common terminal and the earth ground.
