Suggested Actions
This error will disappear when the
temperature returns to the range
between 0°C and 50°C (32°F to
122°F).
Unplug the AC adapter and
reconnect it. If Er4 still appears,
contact CO2Meter.com.
Unplug the AC adapter and
reconnect it. If Er5 or Er6 still
appears, contact CO2Meter.com.
1. Unplug the AC adapter and
reconnect. If the "Er8" still
appears, recalibrate.
2. Calibrate the unit. If the "Er8" still
appears, contact CO2Meter.com.
1. Select the correct calibration
value before calibrating.
2. If Er9 still appears, contact
