Triplett Gsm130 Carbon Monoxide Meter User Manual (+ PDF)

Thank you for selecting the Triplett GSM130 Carbon Monoxide Meter. The GSM130 is a digital, pen-style meter, that measures and displays carbon monoxide (CO) concentrations between 0 and 999 parts per million (ppm). The GSM130 can be used for ambient air safety checks of residential areas, appliances, HVAC service on furnaces and hot water heaters, home inspections, and industrial environments where the accumulation of CO is possible.

Features

Adjustable carbon monoxide warning level Dual Display
Long-life electrochemical sensor Audible alarm
Backlit LCD for easy viewing in dimly lit areas Low battery indicator
Auto power off
Included wrist strap and carry pouch

Safety Information

IMPORTANT SAFETY NOTES
The GSM130 Carbon Monoxide Monitor is intended for general purpose Air Quality monitoring only and has not been certified for use pursuant to any state or city safety Carbon Monoxide Alarm or Monitoring requirements.
The GSM130 Carbon Monoxide Monitor has not been tested by an independent lab to comply with UL 2034 or IAS 6-96 standard.
It is the responsibility of the customer to obtain and apply current local, state, and national regulations with regard to CO alarms, monitoring, and testing.
Electromagnetic (EMI) interference may cause erratic meter readings; do not place meter near areas of high EMI when taking CO measurements. Recovery time is required after the meter has been exposed to high levels of CO (the longer the exposure, the longer the recovery time).

Carbon monoxide is life-threatening even at relatively low concentrations; learn and recognize the effects of CO poisoning (see Table below). Do not use this meter as a personal safety monitoring device.

Effects of Carbon Monoxide (CO) Poisoning

Warning: Ensure that the meter is powered on at room temperature and in an area free of CO. If not, the meter will read incorrectly when subsequently measuring CO.

0-1 PPM	Normal background levels
9 PPM	Maximum allowable short term exposure
50 PPM	Maximum allowable continuous exposure level in any 8-hour period, according to OSHA
200 PPM	Mild headache, fatigue, nausea, and dizziness after 2-3 hours
400 PPM	Frontal headache with 1-2 hours, life-threatening after 3 hours
800 PPM	Dizziness, nausea, convulsions within 45 minutes. Unconsciousness within 2 hours. DEATH WITHIN 2 TO 3 HOURS
1600 PPM	Headache, dizziness, nausea within 20 minutes, DEATH WITHIN 1 HOUR
3200 PPM	Headache, dizziness, nausea within 510 minutes. DEATH WITHIN 25-30 MINUTES
6400 PPM	Headache, dizziness, nausea within 12 minutes. DEATH WITHIN 10-15 MINUTES
12800 PPM	DEATH WITHIN 1 TO 3 MINUTES

Button Descriptions

Turn the meter on and off (short press); Select alarm setpoint value (long press from a powered OFF state; release the button when desired alarm limit is displayed)
Turn the backlight on and off (short press); Toggle temperature units (long press during self-test period). Reset Maximum CO value (long press in normal operating mode)

Operation

Power the meter
IMPORTANT: Power the meter in a room temperature environment and in an area free of CO; otherwise the meter will read incorrectly when subsequently measuring CO.
Press the button to power on the meter. The LCD will switch ON and display the programmed CO alarm limit in the primary display and the ambient air temperature in the secondary display (as shown in the LCD description section above). Replace the batteries if the display does not switch ON.
The meter performs a 15-second self-test during which the displayed values will blink. When the self-test is finished, the meter beeps and enters the normal operating mode.

Measurements
The CO15 detects the existence of carbon monoxide (CO) in the environment and displays the reading in parts per million (PPM) in the primary display.

To take a measurement, trace the CO15 around the area of the suspected leak.
The meter indicates the presence of carbon monoxide (CO) in PPM in the primary display. The secondary display indicates the maximum value since powered on.
Long press the “backlight” button while in measurement mode to reset the maximum value.
When high CO levels are detected audible beeper sounds at 25 ppm alert the user to the dangerous CO levels. The higher the concentration of CO, the faster the beeper will sound.
To turn the meter off, press the button. The meter powers off after 15 minutes of inactivity.

Change Temperature Units
The temperature shows on the display during the self-test only. Power the meter in a room temperature environment for the most accurate readings. Long press the button during the self-test to change the temperature units to ºC or ºF.

Alarm Settings
An audible beep sounds at 25ppm alerting the user to dangerous CO levels. Change the alarm limit value by following the steps below.

Turn OFF the meter by pressing the button.
Long press the button until the options display on the screen.
The LCD cycles through these options: 25, 30, 35, 45, 50, 70, 100, 200 ppm.
Release the button at the desired alarm limit value.
The meter enters the self-test mode.

Backlight
The meter features a backlit LCD for use in dimly lit areas. Press the button to power ON and OFF the backlight.

Auto Power OFF
The meter automatically powers OFF after 15 minutes of inactivity.
