wait 5 seconds and switch it on
again.
If the error message persists, return
the simulator to an authorized
service provider.
Er 13 Transistor malfunction.
Er 21 Temperature sensor 1 has
no current.
Er 22 Temperature sensor 1 short
circuit.
Er 23 Temperature sensor 1 leak.
Er 25 Electric potential meter 1
damage.
Er 31 Temperature sensor 2 has
no current.
Er 32 Temperature sensor 2 short
circuit.
Er 33 Temperature sensor 2 leak.
Er 35 Electric potential meter 2
damage.
Er 41 Heater malfunction.
Er 52 The water level in the jar is
lower than normal.
The power supply used is
not adequate.
Fill the jar to the correct liquid volume
of 0.5L.
Use the power supply provided with the
ALCOSIM.
Er 54 Alcohol reference solution
temperature above 34 °C
for longer than 3 minutes.
The ALCOSIM simulator
attempts to restore
temperature to 34 °C. If it
cannot, the heater disables
and an Er 54 message
appears.
NOTE: Use the simulator within room
temperature environments (23 °C ±
5 °C).
Turn the simulator off in order for the
alcohol reference solution to cool down.
Turn it on again when appropriate.
Return the simulator to an authorized
service provider if the error messages
persist and ambient temperature is not
the cause.
Er 55 Alcohol reference solution
temperature above 37 °C.
The heater automatically
