SCOTT INSTRUMENTS MINI-SA PORTABLE 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. The toxic gas concentration is
monitored and shown in the graphic display in parts per million (ppm) of the
atmosphere. The oxygen concentration is shown in the graphic display as a
percent (%). When the gas level exceeds the preset level, alarms actuate
including a pulsing audible alarm tone, flashing LED, and a vibration alarm.
The alarm functions for toxic gases include a Time Weighted Average (TWA)
Alarm and a Short Term Exposure Level (STEL) Alarm.
Other features include AUTO CALIBRATION and self diagnostic capabilities, a HOLD function that displays the lowest level detected, and user
adjustable high and low ALARM SETPOINTS. A battery life indicator constantly monitors remaining battery capacity and a backlight provides visibility in low light situations.
Additional features include a PASSWORD PROTECT menu and a BATTERY SAVER mode.
2.0 OPERATIONAL ENVIRONMENT
The SCOTT INSTRUMENTS MINI-SA Portable Gas Detector is designed to
be “INTRINSICALLY SAFE” suitable for operation in Class I, Division 1, Groups
A, B, C & D Hazardous Locations.

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. A break-away neck strap and rubber boot are also available.
All operations of the instrument are controlled by two push-button actuators
which are large enough to accommodate use with gloved hands. In each
menu screen, “PROMPTS” over each push-button define their use.
The SCOTT INSTRUMENTS MINI-SA INSTRUMENT case is constructed of
high impact resistant, flame retardant plastic. The push-button actuators
and the graphic display overlay are UV and chemical resistant.
The Graphic Liquid Crystal Display (LCD) provides continuous readings of
gas concentration as well as battery life remaining and other information.
Alarm conditions are signaled by an alarm legend on the graphic display, an
audible tone, a flashing light, and an internal vibration. Audible tones for
certain alarms can be suspended for thirty (30) second intervals while others will continue until the unit is reset in an atmosphere that corresponds to
the preset safe values. Alarms can also be configured to be latching or
nonlatching. Latching alarms operate until acknowledged. Nonlatching
alarms clear automatically when the detected gas is on the safe side of the
alarm setting.

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 Time Weighted Average (TWA) Alarm
c) A Short Term Exposure Level (STEL) Alarm.
For toxic gas, the ppm, TWA, or STEL level detected and the “ALARM”
legend will flash alternately.
A graphic battery level indicator appears continuously on the display screen.
The indicator shows battery capacity as ten (10) lines inside a picture of a
battery. Each line represents approximately 10% of battery time remaining.
The battery level indicator flashes when the batteries are low. This will occur
when approximately 10% of battery life remains.
EACH LINE REPRESENTS
APPROXIMATELY 10%
OF BATTERY TIME REMAINING
FIGURE 2
BATTERY LEVEL INDICATOR
An exhausted battery alarm will occur after the last bar disappears. See
Figure 2.
“HOLD ACTIVATED” flashing legend indicates that the HOLD feature has
been selected. The instrument will display the highest reading of a toxic gas
or the lowest oxygen reading. This reading will continue to be displayed until
the HOLD function is reset.

4.2 AUDIBLE ALARMS
The SCOTT INSTRUMENTS MINI-SA has an audible alarm which is activated when any of the following conditions occurs:
- The preset gas alarm level is exceeded (ALARM)
- The Time Weighted Average (TWA) is exceeded
- The Short Term Exposure Limit (STEL) is exceeded
- The battery is exhausted
- The sensor is missing or incompatible
In addition, each time the instrument is turned ON, the audible alarm will
pulse three times.
The following describes the function of the Audible Alarm during the alarm
conditions listed above:
GAS ALARM – The Audible Alarm sounds when a gas concentration is detected that exceeds the chosen alarm level, or when a TWA or STEL alarm
value is exceeded. A repetitive pulsing tone will occur at one (1) second
intervals while the alarm condition exists.
In the LATCHING alarm mode, selected in the Alarm Setpoint Menu, after an
alarm condition has cleared, the alarm indication will continue until the alarm
is acknowledged by depressing a pushbutton. In the NON-LATCHING alarm
mode, all alarm indications clear when the alarm condition clears. In either
mode, the instrument gives an “all clear” signal with three audible beeps,
three flashes of the Red Alarm Light, and three vibration pulses when the
alarm indication is cleared.
When an Audible Alarm sounds, depressing either pushbutton on the instrument will silence the Audible Alarm for thirty (30) seconds. If the original
alarm condition still exists after the thirty (30) second silence period, the
Audible Alarm will sound again. The Audible Alarm can be silenced repeatedly by depressing a pushbutton.
LOW BATTERY – An Audible Alarm tone will pulse once every fifteen (15)
seconds to indicate when less than 10% of battery life remains.
MISSING SENSOR – The Audible Alarm for a missing or incompatible sensor is identical to the pulsing one (1) second tone that occurs during an
ALARM condition. Depressing a pushbutton to acknowledge the condition
turns the unit OFF.
8
4.3 VIBRATION ALARM
An internal vibrating motor activates whenever the Audible Alarm sounds. The
Vibration Alarm operates as a secondary alarm feature in high noise environments where the audible alarm may be difficult to hear.
The Vibration Alarm is reset the same as the Audible Alarm as described in
Section 4.2.
The Vibration Alarm will also pulse briefly whenever the MINI-SA instrument
is turned ON or OFF.
WARNING
THE VIBRATION ALARM DOES NOT FUNCTION FOR THE LOW BATTERY INDICATION.
4.4 ALARM LIGHT
The SCOTT INSTRUMENTS MINI-SA instrument contains a Red Light Alarm
LED (Light Emitting Diode) which flashes whenever any Alarm Condition occurs. It will continue to flash when the Audible Alarm is silenced and will flash
as long as the alarm condition is present. In the LATCHING alarm mode,
selected in the Alarm Setpoint Menu, after an alarm condition has cleared,
the alarm indication will continue until the alarm is acknowledged by depressing a pushbutton. In the NON-LATCHING alarm mode, all alarm indications clear when the alarm condition clears. In either mode, the instrument
gives an “all clear” signal with three audible beeps, three flashes of the Red
Alarm Light, and three vibration pulses when the alarm indication is cleared.
4.5 STATUS LIGHT
The instrument also has a Green Status LED that flashes periodically, indicating continuing instrument operation.
9
5.0 SWITCH FUNCTIONS AND DISPLAYS
All operations on the MINI-SA Portable Detector are controlled by two pushbuttons located on the bottom of the unit. The operations vary depending on
the operating mode and the graphic display appearing above the two switches.
The unit sounds a brief audible “beep” whenever either pushbutton is depressed while the instrument is on. Whenever the instrument is turned ON or
OFF, three successive audible tones will sound and the Red Alarm LED will
flash. The Green Status LED will flash once every fifteen (15) seconds during
instrument operation. When in the BATTERY SAVER mode, the Green Status LED flash rate increases to once every five (5) seconds.

an alarm condition occurs, the instrument will override the setpoint
menu and display the alarm as appropriate. The changed setpoint
will not take effect and the previous settings will be reestablished.
No user menu’s can be accessed when a instrument is in an alarm
condition until the unit is turned “OFF”. When turned back “ON”, if
an alarm state occurs during the first minute of operation, all user
menu’s are accessible.
6.8 TWA / STEL MENU (TOXIC GASES ONLY)
The SCOTT INSTRUMENTS MINI-SA has factory preset “TWA/STEL” alarms.
When the values for these alarms are exceeded, the instrument alarm will
activate as described in Section 4.0. The TWA (Time Weighted Average)
function of the instrument averages the level of toxic gas over an eight (8)
hour period and alarms when the preset TWA value of in parts per million is
exceeded.
29
The STEL (Short Term 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 ppm 25 ppm
Carbon monoxide 100 ppm 25 ppm
Chlorine 1 ppm 0.5 ppm
Chlorine Dioxide 0.3 ppm 0.1 ppm
Hydrogen Cyanide 4.0 ppm 2.0 ppm
Hydrogen sulfide 15 ppm 10 ppm
Nitrogen Dioxide 5.0 ppm 3.0 ppm
Phosphine 1 ppm 0.3 ppm
Suphur Dioxide 5 ppm 2 ppm
To enter the TWA/STEL Menu, depress the “SELECT” pushbutton as described in Section 6.2 when the TWA/STEL Menu screen is displayed. The
instrument will display one of the following screens:
<gas> TWA/STEL MENU
For Toxic Gases STEL = 0 ppm
TWA = 0 ppm @ 0:05
RESET SHOW
DISABLE TWA/STEL
STEL and TWA values are calculated. STEL averages exposure for the
latest fifteen (15) minutes. TWA shows the eight-hour average exposure.
Both measures start from zero when the instrument is turned on. The TWA
reading accumulates total exposure since turn-on or “RESET” and is calculated as if the total exposure occurred in a standard eight-hour shift.
The “RESET/DISABLE” pushbuttons allows the user to reset the values and
time on the display to “0”. One of following screens will be displayed when
the “RESET/DISABLE” pushbuttons are depressed:
<gas> TWA/STEL MENU
TIME AVERAGE VALUES
For Toxic Gases
RESET DISABLE
30
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. If the TWA/
STEL functions are off, one of the following screens will be displayed:
<gas> TWA/STEL MENU
