11 Bars
: > 1150 ppm
12 Bars

13 Bars

14 Bars
: > 4500 ppm
These data are just approximate values and are not for end users information. Since the
LSG/LSK are calibrated with calibration gas at 1000 ppm following statement can be made:
at 1000 ppm the display will be between 9 and 11 bars!
2.4 Sensitivity
The sensitivity can be set to “1/5“ (left bars blinking), “normal” (middle bars blinking) and
“factor 5” (right bars are blinking)..
At „factor 5“ ten bars will be shown already at a concentration of 200 ppm.
2.5 Automatic Switch Off
Should no button be pressed the instrument will switch off after 20 minutes.
2.6 Battery
At all display mode the grey battery symbol will be shown once the battery voltage is be below
2.10V. Below 2.0V the battery symbol will be shown as black.
When the battery voltage is below 1.9V the instrument will switch off..
The operating time without lightning is at approximately 16 hours and at approximately 12 hours
with lightning.
It appears that the contact resistance between the batteries and the clip contacts have a
negative impact on the operating time. . If might be useful to turn the inserted batteries in the
clip contacts several times.
