Error code Cause Recommended action
Err 103 Main battery voltage is critically low.
When this error appears, the data logger
will soon stop radio communication to
conserve energy. It will continue to
record measurement data in the local
memory as long as possible.
Replace the main batteries of the data
logger.
External power supply is connected but
the power switch of the data logger is in
the O position.
Move the power switch to the On
position. Note that it will take some time
for the error to clear if the data logger
remains continuously powered.
Err 104 Incorrect factory configuration
parameters.
Power cycle the data logger. If the error
persists, contact Vaisala.
Err 105 Real-time clock hardware error.
Err 106 Data logger is operating in CO
2
mode
without external power.
Connect an external power supply to the
service port of the data logger to avoid
draining the batteries.
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
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.
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
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.
Err 200 Real-time clock battery voltage is low. Replace the clock battery.
Err 202 Communication failure with at least 1
probe that was detected at startup.
1. Check that the probe(s) are
connected properly.
2. If you reconnected any probes, wait 1
minute 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).
Err 203 Probe error. Can be caused by probe
damage or a wet humidity sensor.
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.
