IDEAL 61-327, Operation And Safety Manual

Page: 19 / 72

Function Description
LCD One LCD. Displays a “-” symbol for all negative readings, displays “AC” for
alternating current or “DC” for direct current.
LCD
Backlight
White backlight. The backlight will automatically power off after 5 minutes
of inactivated
High
Voltage
Alarm
1) Only applicable to ACV / DCV
2) For ACV and DCV, when voltages in excess of 30V is measured or the
measured voltage is over limit, then the high voltage alarm symbol “ . ”
appears on the screen display, simultaneously the LED remains RED and
beeping lasts for 1 second then becomes silent during measurement.
Regular
Prompt
1) When turning the dial switch to any setting position except OFF, the buzzer
will beep one time and the NCV LED flashes one time.
2) When the button selection is valid, the buzzer will beep one time; When the
button is invalid, the buzzer will beep twice.
3) About 1 minute before the automatic shutdown, the buzzer will beep 5
times continuously, and 1 long beep before the unit shuts down.
4) When the automatic shutdown function is canceled, the buzzer will beep 5
times when it reaches the APO time setting.
Over Range
Indication
LCD displays “OL” when over range is encountered.
Low Battery
Indication
When the battery voltage < 3.6 ±0.2V, the low battery indication ‘ ‘ is
displayed on the screen and the meter will still work normally. When the
battery voltage drops to less than 3.1 ±0.2V, “bAtt” is displayed for 5 seconds
then shuts off. When the battery voltage is less than 2.3V, accuracy is no
longer assured.
APO The unit will be automatically power off after 30 minutes of inactivity and
enter the low-power state. Current draw is approx.
≤
50 micro A.
Restore
APO
All the buttons can wake up the unit, rotate the dial switch to any setting
except OFF to wake it up.
Disable
Auto Power
Off Function
Pressing the “HOLD” key while turning on the unit on at the same time, will
cancel the auto shutdown function. Buzzer will beep 5 times and the LCD will
not display the “APO” symbol.
Mechanical
Housing
Single Injection Molding with rubber boot.
