Key Protect Level
It is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the key protect level (KP-1 to KP-7) when the
key-protect switch is set to ON.
The key protect level is set in the function setting mode. The key protect indicator is lit when the key-protect switch is ON.
* Changing mode to configuration selection mode or function setting mode.
Self-diagnostic Function
The following displays will appear if an error occurs.
*1. Displays for 4-digit models are given in parentheses.
*2. This includes times when the life of the EEPROM has expired.
*3. This occurs if the present value or total count value falls below −99999
(−999 for 4-digit models).
*4. This occurs in the following conditions if the present value (i.e.,
measurement value) exceeds 999999 (9999 for 4-digit models).
• For Output Modes K-2, D, L, or H
• Dual counter or tachometer operation is used.
*5. Display flashes.(1-second cycles)
*6. This does not apply when tachometer operation is used.
*7. This is displayed if the alarm value setting for either of the two outputs is
exceeded if a model with two outputs is used.The total ON count will not be
cleared by using the Reset Key.
*8. The normal display and e3 will appear alternately.
When the Reset Key is pressed, e3 will not be displayed even if the alarm
set value is exceeded.
(Monitoring is possible, however, because the counter will continue without
the output ON count being cleared.)
