8. Maintenance and troubleshooting
8.1 Cleaning
You can clean the Indigo transmitter body by wiping it with a moist cloth. Standard cleaning
agents can be used.
Refer to the probe-specific cleaning instructions when cleaning the probe
connected to transmitter. Do not spray anything directly on the probe, since that
may deposit impurities on the sensor.
Chemical tolerance
The following chemicals can be used to clean the transmitter:
• H
2
O
2
(6000 ppm), non-condensing
• Alcohol-based cleaning agents such as ethanol and IPA (70 % Isopropyl Alcohol, 30 %
water)
• Ca(Clo)
2
(calcium hypochlorite) max. 0.5 %
• QAC (quaternary ammonium cations) max. 0.5 %
Avoid exposing the transmitter to chemicals for unnecessarily long periods of
time. Do not immerse it in a chemical, and wipe chemicals off the surfaces after
cleaning.
8.2 Replacing probes
Only connect compatible measurement devices to the transmitter.
Attempting to connect incompatible devices or cables can damage the
equipment. Refer to transmitter specifications for compatibility information.
CAUTION!
You can replace probes both when transmitter power is on and when it is off. There is no need
to disconnect any wires from the transmitter; just detach the probe from the probe cable
connector (5-pin M12).
When you replace a probe, measurement parameters and outputs will behave differently
depending on whether the new probe's parameters are the same as the parameters of the old
probe:
• If you replace a probe with a new one that has the same measurement parameters as the
removed probe, the transmitter will continue to show those measurements once it detects
the new probe.
• If you replace a probe with a new one that has different measurement parameters as the
removed probe, you need to reconfigure the analog outputs for the new probe. The
measurement parameters shown on the transmitter display will be changed automatically.
