Cases in Which Voltage Adjustment Is Made
(1)
When the “AD FULL” error occurs during a measurement:
This may occur when the temperature in the instrument has risen after it is used in hot
environment or exposed to direct sunlight for a long time or in a similar case.
Turn off and on the power and readjust the voltages to 2.5 V.
(2)
When the “LAMP BROKEN” error occurs during a measurement:
This may occur because of the deterioration of the lamp or dirt in the instrument.
Consult with our agent or service department.
When you want to use the instrument temporarily, measurements can be made by
turning off and on the power and readjusting the voltages to 2.5 V.
*
In that case, take sufficient care because the full performance of the instrument may
not be obtained.
(3)
When the signal voltage or reference voltage is 1.0 V or less:
When only the signal voltage has lowered, the inside of the instrument has possibly
been contaminated. In this case, even when measurements are continued, it is
impossible to obtain precise and accurate results.
Consult with our agent or service department.
When both reference voltage and signal voltage have lowered, the cause may be
measurements at a low temperature or the deterioration of the instrument.
Although even when measurements are continued they are not affected, we recommend
the voltage adjustment to prevent an unexpected error because of a voltage drop during
a measurement.
(4)
When the signal voltage and reference voltage are 4.0 V or more:
This may occur when measurements are made at a high temperature.
Although even when measurements are continued they are not affected, we recommend
the voltage adjustment to prevent an unexpected error because of a voltage rise during
a measurement.
