Countermeasure
The battery is inserted
incorrectly.
Check the orientation of
battery.
Check the orientation of battery as
shown in the case and if it is
incorrect, reinsert the battery.
1
There is no
display.
The battery is running
out.
Check how much battery is
left.
Replace with a new battery.
The battery is running
out.
Check for battery low display. Replace with a new battery.
2
The display
appears, but
immediately
disappears.
The auto power-off
mode is working.
Check the operating time has
passed 5 minutes.
Press the POWER button with the
power supply off for 6 s. at least, and
extend the continuous operation
time to 15 minutes.
A charge over ±5%F.S.
of the default zero
point is given to the
sensor during zero
clear operation. (Er1)
The display during zero clear
operation is ±5%F.S. at max.
Return to a condition with no
charge, and retry zero clear
operation.
The sensor is broken.
(Er2)
Stop using immediately and contact
SMC.
Error in internal data.
(Er3)
Turn off the power supply once, and
turn it on again.
Ask SMC to investigate if the error
persists.
The upper/lower limit
of the measurable
voltage range is
exceeded.
(HHH/LLL)
Check the measured value is
displayed when the charged
object is kept far away from
the sensor.
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.
3
An error display
is shown.
The measuring
distance is not
appropriate.
(HHH/LLL)
Check the measuring
distance referring to the label
on the sensor (50 mm).
Adjust the distance between the
measured target and sensor to the
rated value (50 mm).
4
The displayed
value does not
change.
The peak hold mode
or bottom hold mode is
set.
Check whether the LCD is
displaying "P" for peak hold
mode or "b" for bottom hold
mode.
Hold the POWER button pressed
until "P" or "b" disappears, and then
move to the instantaneous display
mode.
5
The displayed
value is
unstable.
The ground wire is not
grounded.
Check the ground wire is
connected properly.
Ground the ground wire.
The ground wire is not
grounded.
Check the ground wire is
connected properly.
Ground the ground wire.
6
The zero point
is displaced.
Ambient environment
is charged.
Measure in an open place
like outside of a room, and
check the zero point returns.
Execute zero clear operation.
7
The back light
does not turn
on.
Operating
environment is too
bright to see.
Check the back light is on in
a dark place.
If the light is confirmed to be off, ask
SMC to investigate.
