Error code Cause
Err 104 Incorrect factory configuration
parameters.
Err 105 Real-time clock hardware error.
Err 110 If using 1 probe with the data logger:
• No probe connected at startup
• Incompatible probe detected
• Trying to switch from two-probe mode
to one-probe mode without
performing a factory reset
If using 2 temperature probes with the
probe splitter:
• No probes connected at startup
• Two probes connected at same time
without following proper setup or
probe swap procedure
• Data logger is in two-probe mode but 1
probe is missing
• Unsupported probe combination
• At least 1 incompatible probe detected
Err 200 Real-time clock battery voltage is low.
Err 202 Communication failure with at least 1
probe that was detected at startup.
Err 203 Probe error. Can be caused by probe
damage or a wet humidity sensor.
Err 204 Real-time clock temperature
compensation problem.

Recommended action
Power cycle the data logger. If the error
persists, contact Vaisala.
1. Verify that a compatible probe is
connected to the data logger.
2. Power cycle the data logger to re-
detect the probe.
3. If the error persists, it is likely that the
data logger has been set up in two-
probe mode. Perform the factory
reset procedure to allow one-probe
use again, then power cycle the
logger to re-detect the probe.
1. Verify that that probe splitter and 2
supported temperature-only probes
are connected to the data logger.
2. If you reconnected any probes, power
cycle the data logger to re-detect the
probe(s).
3. If the error persists, perform the two-
probe setup again.
Replace the clock battery.
1. Check that the probe(s) are
connected properly.
2. If you reconnected any probes, wait
1minute for the display to update and
verify that the error is gone.
3. If the error persists, power cycle the
data logger to re-detect the probe(s).
Inspect the probe and replace it if
necessary. If the error has been caused
by a wet humidity sensor, wait for it to
dry out.
If error code Err 200 is also active,
replace the clock battery. If the error
persists, contact Vaisala.
