3. Other Functions
3.1 Sleep Function
This is a function to prevent the instrument from being left powered on in
order to conserve battery life. This function causes the instrument to enter
the Sleep (powered-down) mode about 30 minutes after the last switch or
button operation.
To exit the Sleep mode, turn the Function Selector switch back to "OFF",
then to any other position, or press any button.
The current is consumed a little in the Sleep mode.
NOTE
● Connecting the plug to the OUTPUT terminal disables the Sleep
function. The function is enabled on removing the plug from the terminal.
● The Sleep function is disabled in the PEAK measurement mode.
3.2 Data Hold Function
This is a function used to freeze the measured value on the display. Press
the Data Hold button to freeze the reading. The reading will be held regard-

ner of the display while the instrument is in the Data Hold mode.
To exit the Data Hold mode, press the Data Hold button again.
NOTE
If the instrument in the Data Hold mode goes into "sleep", it will return to
the normal mode.
3.3 LoHz Function
In ACV or ACA range, if frequency of the voltage or current under
test is 40Hz or lower, the display indicates "LoHz" and sample rate is
automatically switched from the normal 3 times/sec to 2 times/sec to
reduce fluctuation of the reading. "LoHz" is also indicated where input is
3% of full scale or less.
