Fault Description Suggested Actions
1
Er3
The ambient temperature
has exceeded the
temperature range 0°C
to 50°C (32°F to 122°F)
This error will disappear when
the temperature returns to the
range between 0°C and 50°C
(32°F to 122°F).
2
Er4
Inaccurate measurement
or the sensor has
exceeded its expected
life
Unplug the AC adapter and
reconnect it. If the “Er4” always
appears, please contact place
of purchase.
3
Er5
Er6
EEPROM System
Problem
Unplug the AC adapter and
reconnect it. If the “Er5, Er6”
still appears, please contact
place of purchase.
4
Er8
The accuracy of CO2
sensor may deviate from
the actual concentration.
①Unplug the AC adapter and
reconnect. If the “Er8” still
appears, please contact place
of purchase.
②Calibrate the unit. After
calibration if the “Er8” still
appears, please contact place
of purchase.
5
Er9
Calibration failure caused
by too large a difference
between the calibration
value selected and the
CO2 level read during
calibration.
① Select the correct calibration
value before calibrating.
② If Er9 still appears, please
contact place of purchase.
