1000ppm) or exhaust gases. Continuously low calibration check results or fluctuation of zero readings may indicate sensor end of life or failure. Consult SENSIT Technologies with any questions. For best accuracy always zero in clean air environments similar in temperature and relative humidity to the environment where the instrument will be used. - Page 3 WARNING: To reduce the risk of ignition of a flammable atmosphere, batteries must only be changed in an area known to be nonflammable. AVERTISSEMENT: Pour réduire le risque d’allumage d’une atmosphère inflammable, des batteries doivent seulement être changées dans un secteur connu pour être inflammables. Do not mix batteries of different age or type.

Page 7: General Description
GENERAL DESCRIPTION The TRAK-IT® IIIa GLT is designed to be used in conjunction with a GLT tablet computer. The paired instrument-tablet system allows users to be trained in a hazardous gas free environment. The trainer monitors each instrument with a tablet computer running specialized software that allows real-time data to be streamed via Bluetooth from the instrument. - Page 8 GENERAL DESCRIPTION All TRAK-IT® IIIa GLT instruments incorporate a low power catalytic sensor to measure combustible gases in the LEL (lower explosive limit) range and a separate advanced thermal conductivity sensor to measure percent volume (%v/v). An automatically backlit display shows gas concentrations for all sensors installed.

Page 13: Battery Installation/Replacement
BATTERY INSTALLATION/REPLACEMENT A battery strength icon is located at the lower right corner of the display which indicates the approximate battery capacity. Battery replacement is necessary when the display reads BAT LOW (4.25 Volts), an audible alarm sounds and the green ready LED flashes. When the instrument remains in BAT LOW, a count down will appear starting at 300 seconds (5 minutes) which is the maximum time remaining before shut down. -
Page 14: Operation And Use
NOTE: Instrument must be used in monitoring mode in order to read live gas. 1. Push the POWER/MUTE BUTTON (A) until the instrument beeps and the display illuminates. Each of the following will be displayed: a. Sensit Technologies Logo b. System check that includes: LED check Backlight check iii. - Page 15 OPERATION AND USE 2. If you are not using the instrument along with a GLT tablet, press and release any button on the “Wait for Trainer” screen to select monitoring mode and continue the start-up process. 3. If the display fails to illuminate or BAT LOW is shown on the display, replace the batteries.
- Page 16 OPERATION AND USE 7. Prior to use, test the integrity of the sample system. Use your finger to block the inlet of the probe assembly for 4-5 seconds. The display will read FLOW BLOCKED if all seals are intact.During pump flow block, a beep will occur every 2 seconds until the pump restarts and adequate flow is present.
- Page 17 OPERATION AND USE The standard factory preset LED indicators and alarm points are: a. Combustible gas: Methane, audio and visual alarm indicators from 10% LEL to 100% LEL. METHANE: 50% LEL Methane to 17% volume* Methane (LED indicator only above 17% volume Methane) *When equipped with percent volume sensor.
- Page 18 OPERATION AND USE 12. At any time the operator may save the readings on the display by pressing the ZERO/SAVE BUTTON (C). This will save all readings for download at a later time. Log size is factory set to store 6 logs, but can be increased up to 100 logs.
