Then the message “Ready..” is displayed (see figure below). At this point, the user has two options: (1) step through the operation menu (see below), or (2) take a measurement (see page 16).
- Page 4 OPERATION The displays are arranged in a “round robin” order: To choose a specific display, press the [MODE] key one or more times until the desired display appears. Ready Mode xxx ppm/ppb PC comm? Peak Cancel background? xxx ppm/ppb Run Time Gas= hh:mm Log on/off?
- Page 5 OPERATION “Ready..” To choose a specific display, press the [MODE] key one or more times until the desired display appears. Taking a measurement: There are two ways to start a measurement: (1)operating in the Hygiene mode and (2) manually starting and stopping measurement in the Survey mode.

PROGRAMMING 4.1 Programming Mode The programming mode allows users to change the setups in the monitor, calibrate the monitor, modify the sensor configuration and enter user information, etc. The programming mode has four menu items. Each menu item includes several sub-menus to perform additional programming functions. - Page 9 PROGRAMMING This procedure determines the zero point of the sensor calibration curve. To perform a zero air calibration, connect the tube adapter, break off both ends of a VOC zeroing tube and insert the tube into the adapter. 1. Press the [Y/+] key at the "Zero Cal?" prompt to start the zero calibration 2.
- Page 10 PROGRAMMING 4.4.2 Span Calibration This procedure determines the second point of the sensor calibration curve for the sensor. A cylinder of standard reference gas (span gas) fitted with a 500 cc/min. flow- limiting regulator or a flow-matching regulator is needed to perform this procedure.
- Page 11 PROGRAMMING 4.4.4 Changing the Span Value Note: The minimum span gas concentration is 1 ppm. This function allows the user to change the span values of the calibration gases. 1. “Change Span Value?” is the fourth sub-menu item in the Calibration sub-menu. 2.
