Error codes

The HP-200 has a capability of displaying various error codes.
An error code is displayed on the auxiliary display part while blinking.

ERROR
E-92 3
More than one error cannot be displayed at a time. If multiple errors occur, the error having the higher priority
*1:
level (smaller number) is displayed.
For E-11 to E-15, re-calibration can be performed. However, if any of E-21 to E-25 occurs during calibration,
*2: no re-calibration can be performed.
Take remedial action in accordance with " Remedial action for error codes " (page 72).
*3: If no temperature electrode is used (temperature sensor type is set to "non," no error is displayed.
For the relationship between errors, alarm output, FAIL signal output, cleaning output, and transmission
output, see " Output conditions for various output types " (page 63).
Tip
When an error code is displayed, the HOLD indicator blinks and transmission output becomes the
output value specified on the Setup menu. See " Set currently held value for transmission output 1 "
(page 36) and " Set currently held value for transmission output 2 " (page 37)
Error

Response speed The response of the pH electrode is low during
error calibration using a standard solution.
Electrode The sensitivity of the pH electrode decreases
sensitivity error during calibration using a standard solution.
Asymmetry Electromotive force (asymmetry potential) for pH7 is
potential error large during calibration using a standard solution.
Standard solution
The specified standard solution is not used.
