The SafeGuard has a simple one button operation. To turn on or off the instrument press and hold the
button. The unit will initially display its serial number and firmware version:
It will then display the sensors fitted and when they were last calibrated. If the sensors are within their
recommended calibration period the date will be in green, any sensors outside their calibration period
will have a date in red.
The instrument will then enter a start-up mode for 2 minutes. During this period the sensor readings
will be adjusting and then stabilising to the measured supply. During the start-up period sensor
readings and the edge lighting will be in blue.
Press once to clear a notification or mute the alarm. Once the start up period has been completed
the sensors will then display and datalog the live readings.
