7. Functions of Keys and Automatic Power-off
• SELECT: Selects functions in the trigger mode. When two or more measurement functions are
combined at the same position, press this key to switch between the functions
• HOLD: Holds readings in the trigger mode. Press this key to lock the displayed value and press it
again to reset the locking state and then enter the normal measurement state
• REL: Measures relative values in the trigger mode. Press this key at the DCA position to set as
reference the currently displayed value and automatically reset the LCD display. In the subsequent
measuring results, the reference value will be automatically deducted until the relative value
measurement function is exited by pressing this key again.
•
Automatic power-off function: The meter will automatically “Power Off” after idling for 15 minutes.
To reset, press any function key (for effective key operations, see VIII) or rotate the function/range
selection button, then the meter will automatically “Power On” and enter the measurement status. To
power off the meter, hold the SELECT key, then the automatic power-off function will be cancelled.
“Auto Power-off” represents a sleep status. In such state, a small amount of current (approximately
5μA) will be consumed. If the meter is not used for long, be sure to shut off its power.
• Buzzer Function: Press any function key at any position; if such key is valid, the buzzer will sound; if
invalid, the buzzer will not sound; the buzzer will give 5 continuous warning sounds for 1 minute and
then 1 long buzz sound just before it powers off. The buzzer sounds at the continuity measurement
when the resistance is less than 50.
• Effectiveness of Keys - Not all key operations are effective at all positions. Only the correct key
operation can change the operation function or wake up the sleeping clamp multimeter. See the
following table for details ( �means effective):
