Retaining Data during Power Interruptions
Data is written to EEPROM when the power is turned OFF. The write
life is 1,000,000 writes min.
Self-diagnosis
The following indications will be made when an error occurs.
Try correcting the error by cycling the power supply. If the indications
do not change, try inputting the reset signal. If that does not work, the
Counter will need to be repaired. If normal operation is recovered, it
might have been caused by noise. Check for noise generation.

mounting screw. Press by the hand the front panel as indicated by
the arrow so that the screw will tighten securely.
display
A DIP switch on models with 4, 6, or 8 digits could be used to set
the maximum counting speed to 3 kHz, 5 kHz, or 30 kHz. The
upgraded models have been changed so the maximum counting
speed can be set to 5 kHz or 30 kHz.
Interruptions
On models that back up data when power is turned OFF (models
with model numbers ending in “-M”), a DIP switch setting has
been provided to enable or disable backup.
Some of the functions allocated to the DIP switches have been
changed to allow for the changes described in 1 and 2, above.
