G-TECTA™ 4GP – Product Features

Operation

Switching on

The G-TECTA™ 4GP is designed to be very easy to

operate. Please follow these simple steps to ensure

your instrument is ready for use:

Step 1

W A R N I N G



Ensure the instrument is in clean air.

Step 2

Press and hold the mode button for approximately

2 seconds until the red LED ﬂashes on the

instrument. The display screen will light up and

the instrument will begin its start up sequence.

G-TECTA™ 4GP Start-Up Sequence

The instrument will test the alarm LEDs, the alarm

sounder, the vibration alarm and the display screen.

The sounder may be silenced by pressing the mode

button once.

The instrument will continue through a start up sequence

as shown below, this will take approximately 45 seconds.

During the start up sequence, check the battery

display to ensure you have enough charge to use

the instrument.

Note: During the start up sequence the next

calibration date will be displayed.

If the calibration due date has expired, the

G-TECTA™ 4GP instrument will display a warning

message that calibration is due. As a default the

instrument can still function, however the G-TECTA™ 4GP

can be conﬁgured to automatically shut down using

G-TECTA™ PC software if required. The Linde Group

strongly recommends that instruments are calibrated

as soon as possible once the calibration date is due.

Auto Zero*

The Auto Zero function is enabled as a default

setting. During start-up, the instrument will display

Auto Zero and “????”. Press the mode button to

conﬁrm the Auto Zero function.

and dry, between temperature ranges 0-30°C, and

at a humidity level of 20-90%RH.
