Figure 16 Detection Of A New Rh + T Probe Shown On Display - Vaisala VaiNet RFL100 User Manual

4. Operation
4.1 Probe detection
Probe detection of RFL100 has been changed to accommodate two probe operation. In
firmware version 1.2.0 and later, the data logger detects and validates the connected probe(s)
only at startup. If any unsupported probes or probe combinations are detected, or if both
probes have been replaced simultaneously in two probe use, an error is shown. The only way
to recover is to turn off the data logger and correct the problem.
After the probe detection is successfully completed, the data logger starts its normal
operation. The detected and validated probe(s) must remain the same until the data logger is
turned off again. If a probe is disconnected while the data logger remains powered on, a
connection error will be shown. Reconnecting the same, correctly detected probe without
turning off the data logger is supported.
Remember the following when operating and maintaining the data logger:
• Changing a probe to a different one always requires the data logger to be
turned off.
• In two probe operation, probes must be replaced one at a time according to
the replacement procedure.
