malfunction. Check the integrity of the humidity probe
and the probe cable. Clean the probe from
dirt, water, ice or other contaminants.
E1 Humidity sensor short circuit
E2 Humidity sensor open circuit Check the integrity of the humidity probe
and the probe cable.
E3 Temperature sensor open circuit.
E4 Temperature sensor short circuit. Check the integrity of the humidity probe
and the probe cable. Clean the probe from
dirt water, ice or other contaminants. E5 Temperature measurement
malfunction
E6 Temperature sensor current leak. Check the integrity of the humidity probe
and the probe cables. Clean the probes
from dirt, water, ice or other contaminants.
E7 Internal ADC read error Internal transmitter failure. Remove the
transmitter and return the faulty unit to
Vaisala Service.
E8 Additional temperature sensor
short circuit Check the integrity of the temperature
probe and the probe cable. Clean the

1 (or 2)
Disconnect the power and check the
module connection.
E26 Communication module installed
in incorrect add-on module slot Disconnect the power and change the
communication module to another module
slot.
E27 Pressure out of valid range Check that assumed pressure is within
measurement range for the transmitter.
E28 … E29 Unknown/incompatible module
installed in add-on module slot 1
(or 2)
Ensure that the module is compatible with
the PTU300.
E30 Internal analog voltage out of
range Internal transmitter failure. Remove the
transmitter and return the faulty unit to
Vaisala Service.
