Turning On/Off MEASURE Mode
Pressing the
key after power-on turns off the MEASURE
mode.
•
If the MEASURE mode is not needed and therefore turned off,
power to the measurement circuit is also turned off within the cali-
brator. Thus, you can save on battery power if the calibrator is
running on batteries.
•
Turning off the MEASURE mode causes the on-screen measured
value to disappear.
•
To resume measurement when the MEASURE mode is off, press
the
key once again.
TIP
One to two seconds are taken for the LCD to turn on after the MEASURE mode is
turned on.
■
Automatic Power-off
• When the calibrator is running on batteries and no key is operated for
approximately nine minutes, all elements on the LCD begin to blink.
The calibrator gives off a buzzer sound to alert you. If you still do not
operate any key for another 30 seconds, the calibrator automatically
turns off. The automatic power-off feature is factory-set to ON.
• To continue using the calibrator after the LCD has begun blinking,
press any key other than the
key. The LCD stops blinking and
lights steady, allowing you to continue from the original status of the
calibrator.
• The automatic power-off feature is disabled if the calibrator is operated
on the AC adapter.
• To disable the automatic power-off feature when the calibrator is bat-
tery-operated, see Section 7.8, “Disabling the Automatic Power-off
Feature.”
