4 SCOTT INSTRUMENTS MINI-SA PORT ABLE GAS DETECTOR 1.0 INTRODUCTION The SCOTT INSTRUMENTS MINI-SA Portable Gas Detector is a self contained instrument designed to detect and provide audible, visual, and tactile indication of the presence of oxygen or toxic gas in the air .
5 3.0 GENERAL INSTRUCTIONS 3.1 UNP ACKING Remove the SCOTT INSTRUMENTS MINI-SA instrument from its packaging and examine it for external damage. If any damage is found, notify your SCOTT INSTRUMENTS distributor , sales representative, or the SCOTT IN- STRUMENTS Service Department.
6 4.0 INSTRUMENT DESCRIPTION THE SCOTT INSTRUMENTS MINI-SA INSTRUMENT is designed for use as a personal monitor . The MINI-SA is equipped with a snap mounting clip for ease of use.
7 4 . 1 ALARM LEGENDS The following alarm legends appear in the graphic display: “ALARM” flashing legend indicates one of the following: a ) Gas concentration which exceeds the preset level b ) A T ime Weighted A verage (TW A ) Alarm c) A Short T erm Exposure Level (STEL) Alarm.
8 4.2 AUDIBLE ALARMS The SCOTT INSTRUMENTS MINI-SA has an audible alarm which is acti- vated when any of the following conditions occurs: - The preset gas alarm level is exceeded (ALARM) - The T ime W.
9 4.3 VIBRA TION ALARM An internal vibrating motor activates whenever the Audible Alarm sounds. The V ibration Alarm operates as a secondary alarm feature in high noise environ- ments where the audible alarm may be dif ficult to hear . The Vibration Alarm is reset the same as the Audible Alarm as described in Section 4.
10 5. 0 SWITCH FUNCTIONS AND DISPLA YS All operations on the MINI-SA Portable Detector are controlled by two push- buttons located on the bottom of the unit. The operations vary depending on the operating mode and the graphic display appearing above the two switches.
11 6.0 OPERA TING INSTRUCTIONS Before using this instrument, read and understand ALL instructions for ALL operating modes described in this Section. Prior to use, the instrument should be checked for proper calibration as described in this Section.
12 6. 1 INSTRUMENT TURN ON / OFF T o turn the instrument ON, depress either pushbutton. Three successive “beeps” will sound. The Red LED will flash and the vibration alarm will pulse for each “beep.” The graphic display will show one of the following screens while the instrument initializes.
13 sensor type has been changed or if the previous calibration was not suc- cessful, the bottom line of the display will show “CALIBRA TION REQUIRED”.
14 6.2 MENU SELECTION From the Operating Mode screen, there are six menus that can be selected by the user . They are “ZERO CALIBRA TION,” “SP AN CALIBRA TION,” “PEAK/ HOLD,” “ALARM SETPOINT ,” “TW A/STEL,” and “CONFIGURA TION.
15 PEAK / HOLD NEXT SELECT T o go to the PEAK/HOLD menu, depress the “SELECT” pushbutton. T o go to the next menu, depress the lef t pushbutton below the “NEXT” com- mand and one of the follow.
16 CONFIGURA TION NEXT SELECT T o go to the CONFIGURA TION menu, press the “SELECT” pushbutton. T o go to the next menu, depress the lef t pushbutton below the “NEXT” com- mand and the ZERO CALIBRA TION for toxic gas or AUT O CALIBRA TION for oxygen screen will again be displayed.
17 6.3 ZERO CALIBRA TION MENU The MINI-SA instrument can be Auto Zeroed at any time. An Auto Zero should only be performed in an area known to be free of toxic gas or any known cross sensitive materials. See Section 8.0 for SCOTT INSTRUMENTS sup- plied calibration gas cylinders.
18 6. 4 SP AN CALIBRA TION MENU FOR TOXIC GAS ONL Y Note: The MINI-SA software requires that an “AUTO ZERO” be performed as described in Section 6.
19 Calibration cylinders supplied by SCOTT INSTRUMENTS contain 25 PPM H 2 S or 50 PPM CO. T o use another certified concentration, depress the left pushbutton below the “CHANGE” command.
20 This screen will remain on until the instrument detects calibration gas. If no calibration gas is detected after thirty (30) seconds, the instrument will sound a single beep and return to the operating mode. Depressing the “EXIT” pushbutton will also return the instrument to normal operation with no calibration having occurred.
21 Attach the hose of the Adapter to the calibration gas cylinder and begin flowing gas to the cap at a flow rate of 500 cc/min. (300 cc/min. for C l 2 and ClO 2 ).
22 Note: SCOTT INSTRUMENTS supplies T eflon®-lined tubing with all chlorine and ammonia calibration kits. Sticky gases such as chlorine and ammonia require this tubing be used for calibration. Using tub- ing of another type may inhibit the automatic calibration of a MINI-SA and lead to improper readings or a false failed sensor message.
23 6. 6 PEAK / HOLD MENU The MINI-SA can be set to display either the lowest and highest gas reading (PEAK) or just the highest toxic gas or lowest oxygen reading (HOLD) during use. T o enter the PEAK/HOLD menu, depress the “SELECT” pushbutton when the PEAK/HOLD menu is displayed as described in Section 6.
24 4 For T oxic Gases MAX = <_> ppm MENU 20 For O 2 MAX = 21.5 % MIN = 20.9 % MENU Current and peak readings update continuously while this screen is dis- played.
25 NOTE: After an Alarm Condition occurs and the Audible Alarm is si- lenced as instructed in Section 4.0, the instrument will automatically change to the “SHOW PEAK” display to inform the user of the actual level responsible for the alarm condition.
26 6.7 ALARM SETPOINT MENU The “ALARM SETPOINT” can be adjusted by the user in the ALARM SETPOINT menu within the following ranges: C O = 5 to 250 ppm Cl 2 = 0.1 to 10.0 ppm ClO 2 = 0.10 to 2.00 ppm HCN = 0.1 to 50.0 ppm H 2 S = 5 to 100 ppm NH 3 = 5 to 100 ppm NO 2 = 0.
27 the “OK” pushbutton to return to the Operating Mode. T o change the setpoint, depress the “CHANGE” pushbutton. One of the following screens will be displayed: <gas> ALARM SETPOINT For T oxic Gases HI ALARM = <_ >ppm UP DOWN CHANGE O 2 ALARM For O 2 HI ALARM = 23.
28 CHANGE O 2 ALARM For O 2 LO ALARM = 19.5 % UP DOWN T o raise or lower this setpoint, select the “UP” or “DOWN” command. For example, choose “DOWN” and the following screen will appear: CHANGE O 2 ALARM For O 2 LO ALARM = 19.5 % DOWN SET The % value will flash while this screen is displayed.
29 Depressing the “OK” pushbutton will display one of the following screens: <gas> ALARM For T oxic Gases NON-LA TCHING LA TCH OK O 2 ALARM For O 2 NON-LA TCHING LA TCH OK The st atus of the alarms will be displayed as “NON-LA TCHING” or “LA TCHING”.
30 The STEL (Short T erm Exposure Level) function measures the level of toxic gas during a fifteen (15) minute interval and alarms when the preset STEL value in parts per million is exceeded. The alarm levels are as follows: STEL TWA Ammonia 35 p pm 25 p pm Carbon monoxide 100 ppm 25 ppm Chlorine 1 p p m 0.
31 Depressing the “RESET” pushbutton will reset the TWA value, the STEL value, and time all to “0”. The instrument will automatically go back into the Operating Mode and begin collecting measurement data. The “DISABLE” pushbutton turns off the TWA/STEL functions.
32 6.9 CONFIGURA TION MENU The CONFIGURA TION menu of the SCOTT INSTRUMENTS MINI-SA pro- vides the user with the following two (2) optional features: • BA TTERY SA VER mode can extend operational battery life to sev- eral hundred hours by turning off the instrument graphic display dur- ing normal non-alarm operation.
33 If an alarm condition occurs while in the BA TTER Y SA VER mode, the graphic display will come on automatically and remain on until the alarm is reset. After the alarm indication clears, the graphic display will remain on for thirty (30) seconds and then the display will go blank as described above.
34 has been entered, the instrument will display the following screen: P ASSWORD PROTECTION FOR ADV ANCED MENUS TURN CHANGE ON P ASSWORD The MINI-SA is shipped from the factory with password protection off.
35 Use the “UP” and “SET” push-buttons to enter the correct password. Enter- ing the incorrect p assword will display an INCORRECT P ASSWORD mes- sage and allow the user to enter the password again.
36 VERIFY NEW P ASSWORD 5678 UP SET Note: If the pushbutton is not depressed within fifteen (15) seconds, the instrument will beep once and automatically go back to the oper- ating mode and the password will be unchanged. If you wish to change the password shown in the VERIFY NEW P ASS- WORD screen, depress the “CHANGE” pushbutton.
