OPERATING INSTRUCTIONS

STANDALONE MODE

To power on the VOC08, press the PWR button. The LCD will
illuminate and immediately begin scrolling "0s" across the
five positions on the upper readout to indicate that it is
warming up. During the warmup period, the meter will burn
off any dust on the VOC sensor inside the vented ball. If this
is the first use of the meter or if it has not been powered on
in a long while, the warmup period may last as long as
several hours. Normally, it takes 1 to 15 minutes until the
scrolling stops and the upper readout stabilizes.
If you need to make ballpark measurements of mixed-gas
VOC levels over a period longer than 15 minutes (the meter's
Auto Power Off triggering time), you must disable the APO
function.
To power on the VOC08 and simultaneously disable the
APO function while running on battery power, with the
meter off first press and hold the HOLD button, and then
(without releasing HOLD) press and hold the PWR button.
Doing this will cause a small n to briefly appear on the LCD
before the meter powers up with both readouts visible. There
is no permanent on-screen indication that the APO function
has been disabled. So if you disable APO, realize that the
batteries will discharge within an hour or two if you forget to
manually power off the meter after a measurement session.
