GX-3R Pro Operator’s Manual

8. If

ID DISPLAY

is set to

ON

(factory setting is

OFF

, see page 182), the User ID Screen

appears for a few seconds, followed by the Station ID Screen.

9. If the GX-3R Pro experiences a sensor failure during start up, the display shows which sensor

failed and the buzzer sounds a double pulsing tone once per second. In the example below, the
combustible gas sensor failed.

Press and release POWER MODE to acknowledge the failure and continue. “- - - -”
replaces the failed sensor’s gas reading. Replace the failed sensor as soon as possible.

10. If

AUTOZERO

is set to

ON

(factory setting is

OFF

, see page 182), the instrument prompts

you to do an auto zero.

WARNING: Make sure that the instrument is in a known fresh air environment (an

environment free of combustible or toxic gases and of normal oxygen content,
20.9%) before performing an auto zero operation. If you perform an auto zero
operation in an area with gases present, the adjustment will not be accurate.

a. An auto zero operation sets the combustible gas, H

2

S, CO, and super toxic channels to 0

and the OXY channel to 20.9%.

b. If the instrument has a CO

2

sensor installed and if

CO2AIR SETTING

is set to

ON

in

User Mode, the CO

2

channel gets set to 400 ppm (0.04% volume) during an auto zero. If

CO2AIR SETTING

is set to

OFF

in User Mode, the CO

2

channel is not adjusted during

the auto zero.

c. You must press and release POWER MODE to perform an auto zero function. If you do

not press any key, after 15 seconds, the instrument enters Measuring Mode without
performing an auto zero.
