Setup Mode
The setup mode allows the user to customize the meter to his specific needs.
To enter the setup mode, press and hold the MEAS and ON/OFF switches for over 3 seconds when the
meter is switched OFF. All the LCD segments appear and then the meter enters the setup mode.
Tip
To have the changes apply, you need to go through the entire steps from “Setup mode entry” to
“Setup completion” shown below. To leave a setting as it is, just press CAL switch in the setting.
To exit the setup mode with no change of settings, press the ON/OFF switch earlier than pressing
CAL switch in the last step but one, or the “Backlight setting” step.
