CHAPTER 5
SERVICE
5.0 GENERAL
This chapter provides basic service information for the Model CYD211
Temperature Monitor. Factory trained service personnel should be
consulted if the instrument requires repair.
5.1 ERROR
MESSAGES
The following messages appear on the instrument display when it identifies
a problem during operation. The messages are divided into two groups.
Instrument hardware messages are related to the instruments internal
circuits or non-volatile memory. If one of these messages persists after
power is cycled the instrument requires repair or recalibration. Limit
messages are most often associated with over voltage conditions caused by
an improperly selected range or excessive noise on the measurement leads.
If these messages persist after the input or output is configured properly the
instrument may require repair.
5.1.1
Instrument Hardware Errors
ErR 01
Indicates that there is a hardware problem in the instrument
memory. This error is not correctable by the user and the
factory should be consulted.
ErR 02
Indicates there is a soft error in the instrument memory. This
error can be corrected reinitializing memory. Reinitializing
memory sets the instrument to defaults and erases the user
curve. To reinitialize the memory after an Error 02, press both
the
s
and
t
keys simultaneously. The display will blank for
about 5 seconds while the memory is initialized.
ERR 03
Indicates the instrument has lost its calibration. To continue
using the instrument in an uncalibrated state, press the Enter
key after the Error 03 message appears. The Error 03
message is not cleared and will be displayed again on power
up until the unit is calibrated.
ERR 04
Indicates that the A/D converter is not communicating with
the microprocessor. This error is not correctable by the user.
Please contact the factory for instrument return information.
