5.3 ERROR CODE TROUBLESHOOTING
On power up, the CYD201/CYD208 checks internal memory. If a problem
exists, an error message displays on the front panel of the instrument.
Er01
indicates a hardware problem in the instrument memory. This error is
not user-correctable.
Er02
indicates a soft error in the instrument memory. To correct this error,
use the following procedure.
1. Power up the unit and allow it to display Er02.
2. Close DIP Switch 1 (top of the switch pressed in). Leave the switch
closed for at least 5 seconds, then open DIP switch 1 (bottom of the
switch pressed in).
3. Verify the Model CYD201/CYD208 display goes through a normal power
up sequence and then displays 499.9 K.
4. The input(s) of the Model CYD201/CYD208 must now be recalibrated
per in procedure in Paragraph 5.7 before the unit can be used.
OL
indicates a voltage input overload. This can be caused by an open
sensor or diode sensor wired backwards.
Before calling the factory about a persistent problem, try the procedure
below:
