S y m p t o m Confirmation method and remedy

Check that the controller is in the power saving mode.
Check that the interference prevention function is
validated without an interference prevention cable.
Check that if "Master" or "Slave" of the interference
prevention function is set properly.
In case of the holding measurement mode, is a triger
input ?
Check that the trigger settings are correct.
Check that timing signals are supplied.
Check that the displayed setting configures the
upper line for indication of the current value.
Check that the upper and lower lines are
designated in displayed setting.
Check that "hold" is selected for the output delay
setting.
Refer to the troubleshooting method.
Check that cables are connected correctly.
Check that the input method and input voltage are
free from problems.
Check that the sensor head cable length
selection switch is set correctly.
Check that the display scale is set correctly.
Check that zero setting is performed.
Check that analog voltage output scaling is set
correctly.
Isn't BCD output mode selected?
Check that the hold measurement modes and
trigger conditions are configured correctly.
Check that cables are connected correctly.
Check that communication conditions are
entered correctly.
Check that pin layout of the connector is correct.
Check if the upper limit value is set to a negative
value.
Check if zero setting function is used after
reversing the span (inclination) of the displayed
value by using the display scaling function
"SLOPE", "Two-point scaling", "INV", or height
detection mode "hIGht" and also if the lower limit
value is set to a value greater than the offset
value at the detection distance of 0 mm.
Zero setting can be canceled by setting the
upper and lower limit values to correct ones or
by initializing to the factory settings.
