SG Start-Up Sequence
The instrument will test the alarm LEDs, the alarm
sounder, the vibration alarms 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 20 seconds.
Note:
During the start up sequence, check the
battery status symbol to ensure you have enough
battery charge to use the instrument.
Calibration Check
If the instrument is due for calibration in less than
31 days “CAL xx” will be displayed, where xx is
the number of days to the next calibration. When
the date has expired, G-TECTA
®
SG will display the
warning message “CAL”.
When “CAL” is displayed the instrument can
still function as a standard feature, although we
strongly recommend that the instrument is sent
for calibration as soon as possible. Press the mode
button to continue to normal operating mode.
Note: G-TECTA
®
SG can be set to lock in the event of
the CAL date expiring by using G-TECTA
®
PC software.
Auto Zero
The Auto Zero function is enabled as a default
setting*. During start-up, the instrument will display
the Auto Zero confirm screen and the display will
alternate between “Zero” and “????”. Press the
mode button to activate the Auto Zero function.
Note: The instrument will time out in 10 seconds then
change to normal operating mode, without performing
an auto zero, if the mode button is not pressed.
Switching Off
Press and hold the mode button for 5 seconds,
the display will count down until the display shows
OFF. If you release the mode button during the
countdown, the G-TECTA
®
SG will return to normal
operating mode.
* The Auto Zero setting can be configured to operate
automatically, on user confirmation (default), or disabled,
using G-TECTA
®
PC software (see page 15).
