Program operator’s manual for data logging and downloading
instructions.

Buzzer

One solid-state electronic buzzer is located inside the case. Holes on
the top front of the case allow the sound to exit the case. The buzzer
sounds for gas alarms, malfunctions, low battery voltage, and as an
indicator during use of the Gas Tracer’s many display and adjustment
options.

Vibrator

A vibrating motor inside the Gas Tracer case vibrates for gas alarms,
unit malfunctions, and as an indicator during normal use of the
various modes of the Gas Tracer.

Batteries

Three AA-size alkaline batteries (standard) or an optional
rechargeable lithium ion battery pack (3.7 VDC) power the Gas Tracer.
Instrument run time is dependent upon battery type. At 25°C the
alkaline batteries last up to 15 hours and the lithium ion battery pack
lasts up to 10 hours. The battery icon in the upper right of the LCD
shows remaining battery life.

When the Gas Tracer detects a low battery voltage, a low battery
warning is activated. When battery voltage is too low for normal
operation, the Gas Tracer sounds a dead battery alarm.

The alkaline batteries can be replaced by removing the battery cover
on the back of the case. The lithium ion pack can be replaced by
removing the entire battery pack. Push the battery pack latch on the
bottom of the unit toward the front of the unit to release the pack.

The lithium ion battery pack can be recharged by placing the Gas
Tracer in its optional battery charging station or by placing the battery
pack in the charging station.

NOTE: Use of batteries or battery chargers not specified by RKI

Instruments, Inc. will void the CSA classification and may
void the warranty. See “Replacing or Recharging the
Batteries” on page 85.

Data Logging

The Gas Tracer features the ability to log data to its internal memory
and download it to a computer via the infrared communications port
located just below the RESET SILENCE button. It logs bump test data,
calibration data, and event data. No interval trend or alarm trend data
is saved.

NOTE: Although interval trend and alarm trend data are not saved,

the Gas Tracer saves snap log data. For a description of the
snap logging function, see “Snap Log Mode” on page 28.

To utilize the Gas Tracer’s downloading capability, you will need the
Gas Tracer downloading software and a computer with an infrared
port or a USB port that runs one of the following operating systems:
Windows XP, Windows Vista or Windows 7. If your computer has an
infrared port, then no additional accessories are needed to download
data from the Gas Tracer. If your computer does not have an infrared
port but does have a USB port, a USB/IrDA adapter cable can be used
to download data from the Gas Tracer using a USB port. The
downloading software is available from RKI Instruments, Inc. The
adapter cable is also available from RKI or may be purchased at a
computer or electronics supply store.

For a complete description of the downloading software and
procedures for downloading data to a computer, see the GX-2012 Data
Logger Management Program Operator’s Manual.

SDM-2012

The Gas Tracer can be used with the SDM-2012 if desired. The SDM­2012 can charge the instrument if the lithium ion battery pack is being
used. It can also bump test, calibrate, and retrieve saved data. The
SDM-2012 can be operated as a single, stand-alone unit or can be used
with up to 9 other SDM-2012s and operated using a computer. For
more information about the operation of the SDM-2012, see the SDM­2012 Standalone Configuration Operator’s Manual or the SDM-2012
PC Controlled Configuration Operator’s Manual.

10,000 ppm Gas Tracer Operator’s Manual Data Logging • 34

Calibration Mode

Calibration mode allows you to calibrate and bump test the PPM
sensor.

The optimum frequency of calibration depends heavily on how the
Gas Tracer is used. For example, instruments used daily may need to
be calibrated weekly or monthly, while instruments that are used only
a few times a year may need to be calibrated before each use. Typical
calibration frequencies range from monthly to quarterly.

You can program the Gas Tracer to notify you when it is due for
calibration. See “Updating the Calibration Reminder Setting” on
page 72.

Calibration/Bump Test Supplies and Equipment

To calibrate or bump test the Gas Tracer, you will need:

• Known calibrating sample of ppm methane gas

• A demand-flow regulator to provide adequate sample gas flow

• Non-absorbent tubing

• 6-inch humidifier tube

CAUTION:If you are using a calibration kit that includes a gas bag and a

fixed flow regulator or dispensing valve, do not apply gas
directly to the Gas Tracer with the regulator or valve or damage
to the pump will result. See “Appendix A: Calibrating or Bump
Testing with a Sample Bag” on page 97 for instructions to
properly use a gas bag kit.

Preparing for Calibration or Bump Test

Whether you will calibrate the Gas Tracer or perform a bump test, you
will need to set the fresh air readings first.

1. Find a fresh-air environment. This is an environment free of toxic

or combustible gases and of normal oxygen content (20.9%).

2. Turn on the unit as described in “Turning On the Gas Tracer” on
page 16. Use the sample hose and probe.
