Chapter 4 General Operating Instructions
4.1 Introduction
Swiping a magnetic wand past the Edit key, from any of the Data Display screens, displays the Main
Menu . The Up and Down keys maneuver the selection bar up and down and Edit selects the highlighted
item to enter the sub-menus. All items with a sub-menu are indicated by a right facing arrow at the end
of the line. To edit menu item values, swipe the Edit key, and use the Up and Down keys to edit the
value. Once the desired value is entered, swipe the Edit key again to save the value. Swipe the Next key
to reverse out of a sub-menu.
Important
: Some values require a Technician Sequence to be entered to change their
values. This is to prevent the operator from inadvertently changing the values. When
prompted to “Enter technician sequence:” simply swipe the Up key four times to unlock the
value for editing.
4.2 General Setup for the SensePoint
After ensuring proper installation perform the following steps:
1. Apply power to the gas detector
2. Verify the detector has begun startup.
Note : Once the detector is on the data screen, you may notice high or low values out of the full-scale
range. These values should quickly return to the zero-gas value if no gas is present. No false alarms
should be indicated at this time as the zero-gas value will be transmitted by the detector during the
user-defined warmup delay period (up to 5 minutes).
3. Using the magnetic interface, navigate the menus to ensure:
a) Alarm levels for Alarm 1, 2 and 3 are set to the desired value
Note : SensePoint gas detectors have standard relays, which should also be set up at this time. When no
relays are installed, alarms are indicated only by the display color.
b) Time and date are set correctly
c) Engineering units are set to the desired value
d) Calibration span gas value is set to the value of the calibration gas that will be used to
perform initial calibration
e) Calibration marker is set to the desired value (this is the value the output will be held at
during calibration and the calibration purge delay)
4. After sensor has stabilized, perform routine sensor calibration in accordance with Chapter 5 .
