７−１ Sleep Function

CAUTION

●The instrument consumes small amount of battery power in the

sleep mode. Make sure to set the function selector switch to the

OFF position after use.

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.

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.

７−２ 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 regardless of subsequent variation in input. "H" is shown on the

upper right corner of the display while the instrument is in the Data

Hold mode.

To exit the Data Hold mode, press the Data Hold button again.
