Page 9: Start-Up, Shutdown And Always On
4.2 Start-up, Shutdown and Always on Start-up Press and hold the for 3 seconds, the instrument starts to power on. After power on, the instrument automatically enters the visual test, firmware version, 20-second countdown and the second visual test screen, and is accompanied by warning sound and light test. After a short warm-up, it will automatically enter the real-time gas monitoring screen. - Page 10 • When editing a value, once the last value in the range is reached, the display starts again with the first value. • When buttons ( ) is pressed and held more than 1 seconds, the unit leaves configuration mode; it enters operation mode and the home screen is activated. •...

The alarm setpoint can be edited. Value increment = within the sensor measurement resolution STEL alarm setpoint This screen features the status, alarm, sensor type, configuration, and STEL icons, with the current setpoint.
- Page 12 Operation-mode bump test This screen features the status, lock, configuration, and bump test icons, with the selected setting value displayed in the main area. The technician can enable or disable this operation mode feature. When enabled, the instrument operator can bump test the unit from operation mode.
- Page 13 Vibration alarm This screen features the status, alarm, “VIb”, and configuration icons, with the selected setting value displayed in the main area. When enabled, the vibrating alarm will be activated when the unit is in alarm. Values: 0 = disabled ,1 = enabled Operation-mode zero This screen features the status, lock, zero, and configuration icons.

Page 14: Operation Mode
4.4 Operation mode In the operation mode, the worker can scroll through the operating mode loop by continuously pressing the on/off button ( ). The zeroing, calibration, and alarm function test procedures can only be completed if these task settings are enabled for operating mode access。 TWA, STEL (if operating mode access is enabled) and peak readings can also be viewed and cleared. - Page 15 STEL reading This screen displays when the STEL reading is enabled in operation-mode. The screen features the check mark, sensor-type, and STEL icons, and the current STEL reading. Press clear the reading then the value reset to 0 . Initiate bump test This screen displays when operation-mode bump testing is enabled.

Page 16: Bump Test (Or "Functional Test")
4.5 Bump test (or "functional test") Bump testing is a functional test in which an instrument's installed sensors are to be briefly exposed to (or “bumped” by) calibration gases in concentrations that are greater than the sensors’ low- alarm setpoints. This will cause the instrument to go into low alarm and will indicate which sensors pass or fail this basic test for response to gas. -
Page 17: Zeroing
4.6 Zeroing Zeroing adjusts the sensors’ “baseline” readings, which become the points of comparison for subsequent gas readings. It is a prerequisite for calibration. During zeroing, the installed sensors are to be exposed to an air sample from a zero-grade-air cylinder or ambient air that is known to be clean air. -
Page 18: Calibration
4.7 Calibration Regular calibrations promote the accurate measurement of gas concentration values. During calibration, an instrument’s installed sensors are to be exposed to their set concentrations of calibration gases. Based on the sensors’ responses, the instrument will self- adjust to compensate for declining sensor sensitivity, which naturally occurs as the installed sensors are used or “consumed”. -
Page 19: Alarms And Notifications
Take seriously all alarms, warnings, and indicators, and respond to each according to company policy. Alarms T40 II gas monitors have alarms of two different intensities, high and low. Alarms are persistent: they turn off when the alarm-causing event is no longer detected, however, if the instrument’s alarm latch is enabled, an alarm will remain on until the user presses to turn it off. -
