Display

Indicates present values, setting values and abnormal information.
Two types of present values are displayed respectively at the upper and lower parts according to setting.

Mode button

Shifts from Measuring mode to each setting mode.
The destination changes depending on how long the button is held down.
Pressing Mode button for ≥ 2 seconds returns to Measuring mode from each setting mode..

Set button

Shifts the setting value of each setting parameter item to a setting changeable state.
When at setting changeable state, used to move through the digits of setting value for input scaling and toenter (save) the setting value.
Used to release latching alarm in measuring mode (press and hold for 2 sec. or more).

Up button

Shifts through setting parameter items and to increase or select the setting value.

Down button

Shifts through setting parameter items and to decrease or select the setting value.

Configurator Jack

Used to perform configuration with M2EA configurator software (model: M2EACFG).
When using the software, set the Lockout setting of the unit to ‘Lock’.

Refer to the operating manual (EM-5146-B) for detailed procedures.
