Indication of Battery Level
The battery replacement indicator shows the battery level in five stages.
Full battery:
The battery level is below 50% full:
The battery level is below 25% full:
Low battery:
The battery icon flashes in sequence when charging.
Note that the battery replacement indicator is driven by directly measuring the battery voltage when the calibrator is in actual
operation. Consequently, the indicator may read differently depending on the battery load condition (e.g., the load condition
of the source output or on/off state of the measurement function).
To replace batteries and/or fuses refer to Section 12 of this User Guide.
Switching Power ON
Press the Power key once to switch ON the calibrator. Press and hold the Power key for 2 seconds to switch it OFF.
Automatic Power OFF
When the calibrator is running on batteries and no key is pressed for approximately ten minutes, the calibrator switches OFF
automatically. The automatic power-off time can be programmed or set to the factory default state, see the “Global Settings”
section.
Switching the LCD Backlight ON and OFF
Press the backlight key to switch ON the backlight; press again to switch it OFF. Battery life is shortened by backlight
overuse.
Notes:
The backlight automatically switches OFF after 10 seconds. The time can be programmed or reset to the factory
default condition, see the “Global Settings” section.
