It is strongly suggested that the unit be corrected in a
sunny) outdoor environment that is well ventilated± Do
not correct the unit in places crowded with people or
close to areas with high LO
ventilating outlets or fireplaces±
To correct the unit for LO
calibration site and press and hold buttons º and F
simultaneously± The unit will flash continually for about
, minutes) then return to normal operation±
To abort correction at any time) simply turn the meter
off±
CAUTION: The meter is corrected at ambient air of
around ~%%ppm± Do not correct the meter in an
environment with an unknown LO
Doing this could lead to inaccurate measurements±
Relative Humidity Correction
The unit is calibrated with FFV and and >,V salt
solution± It is recommended that the unit is calibrated

Press button F at any time to exit the setup menu±
at º, ºL and at a stable humidity±
To calibrate the unit) plug it into a FFV salt bottle then
press and hold buttons F and ~ simultaneously±The unit
will blink continuously for about D% minutes±
Once this has completed) plug the bottle into a >,V
salt bottle and press button D to begin the next
calibration stage±
It is possible to perform only one calibration test at a
time± To calibrate just FFV salt solution) press button F
after it has finished the first stage± To calibrate just >,V
salt solution) press button º or ~ within , minutes of
FFV calibration having begun±
To abort calibration at any time) simply turn the meter
off±
CAUTION: Do not calibrate the unit without the default
calibration salt± Doing so can cause permanent
damage± Lontact the dealer for calibration salt±
Troubleshooting
Can:t power on
Press button 6 for more than %±F seconds and try
again± Lheck whether batteries are in good contact
and correct polarity is observed±
Fixed readings
Lheck whether data hold function was activated±
Slow response
Lheck whether the air flow channels on the rear are
blocked±
