Countermeasure
Check the orientation of battery as
shown in the case and if it is
incorrect, reinsert the battery.
Replace with a new battery.
Press the POWER button with the
power supply off for 6 s. at least, and
extend the continuous operation
time to 15 minutes.
Return to a condition with no
charge, and retry zero clear
operation.
Stop using immediately and contact
SMC.
Turn off the power supply once, and
turn it on again.
Ask SMC to investigate if the error
persists.
If the measured value is displayed
normally for the object far away fro
the sensor, it means the charge
amount of the measured target is
beyond the specifications of the
product. Stop using immediately.
Adjust the distance between the
measured target and sensor to the
rated value (50 mm).
Hold the POWER button pressed
until "P" or "b" disappears, and then
move to the instantaneous display
mode.
Ground the ground wire.
