Troubleshooting with messages
19.3.5 Message
Error: too low reference impedance
Product-status symbol
Bit status of the PDO pH-state bit 5 = 1
Possible cause The impedance value of the reference electrode is under the set
limit.
The message can only be displayed if the monitoring of the
impedance value has been configured and activated. Refer to
chpt. 10.3.
What to do?
→
As the monitoring of the low limit is not important, make sure
that the parameter Error triggers Activation flags
Low ref. impedance is not selected.
19.3.6 Message
Error: too high reference impedance
Product-status symbol
Bit status of the PDO pH-state bit 4 = 1
Possible cause The impedance value of the reference electrode is above the set
limit.
The message can only be displayed if the monitoring of the
impedance value has been configured and activated. Refer to
chpt. 10.3.
What to do?
→
Replace the reference electrode. Refer to chpt. 17.5.
→
Check if the high warning limit is consistent. Refer to chpt. 10.1.
If the high warning limit is not consistent, send the product back
to Bürkert.
19.3.7 Message
Error: too low leakage current
Product-status symbol
Bit status of the PDO pH-state bit 5 = 1
Possible cause The leakage current of the measuring cell is under the set limit.
The message can only be displayed if the monitoring of the leakage
current has been configured and activated. Refer to chpt. 10.6.
What to do?
→
As the monitoring of the low limit is not important, make sure
that the parameter Error triggers Activation flags
Low ISFET leak. current is not selected.
