How to Quick Start your RKI GX2009

VIDEO TRANSCRIPT:

This is Patrick McCants from the JM Test Systems rental department and today we will be running through a quick start and hit a couple of troubleshooting tips for the RKI GX-2009.

TURNING THE GX-2009 ON
The first thing you will want to do is to power on your GX2009 by pressing and briefly holding the POWER MODE button. At this point you will see the LED lights light up and the screen will turn on and the LCD screen will awaken. You can release the power button once you hear a beep from the monitor.

If you see Cal C-LIMIT on the display, that is indicative that the unit is past due for calibration. Press and release the power button to confirm and continue use.

If you see Fail C-LIMIT on the display, that is indicative that the unit is past due for calibration and will need a calibration before it is operable.

While starting up, the instrument will go through a brief warm up and will show you the date, number of days until next calibration, time of day, battery power, alarm latch setting, full scale values for all channels, warning alarm setting and high alarm settings for all channels, STEL alarms set point for H2S and CO and TWA alarm set point for H2S and CO channels.

If your battery level is showing low or the battery icon is flashing, you will need to charge your instrument before using it.

MEASURING MODE SCREEN
At this point, we see the screen showing all of our current O2, H2S, CO and %LEL readings.

If your readings are not displayed, that means we need to do a fresh air adjustment.

PERFORMING A FRESH AIR ADJUSTMENT
Find a fresh air environment that is free of toxic or normal gas and a normal amount of oxygen. 20.9 ppm is a normal amount of Oxygen.

Secondly, press and hold the AIR button for about 3 seconds. The display will now indicate AIR CAL HOLD AIR. Continue to hold until ADJ and RELEASE are displayed. Release the AIR button and now everything should read 0% except for Oxygen which will say 20.9%

PERFORMING A BREATH TEST
You can perform a breath test on the GX-2009 and quickly test the oxygen sensor, audible, visible and vibratory alarms for proper operation. Performing a breath test is NOT A SUITABLE CALIBRATION OR A SUITBALE BUMP TEST REPLACEMENT.

Cup your hands over the O2 sensor and exhale into the sensor. Your oxygen level should drop below the alarm value of 19.5% and activate the proper alarms.

If the alarms are set to latching, press the POWER MODE button to reset the alarms once the O2 levels are over 19.5%

SENSOR FAILURE
If the GX-2009 experiences a sensor failure during start-up, the LCD display will indicate FAIL. For example, FAIL CO ppm SENSOR. To continue operation, you can press and release the POWER MODE button to acknowledge the failure. All readings for that sensor will be replaced by dashes.

It is absolutely necessary to replace and calibrate the failed sensor as soon as possible.

DISPLAY MODE
Press and release POWER MODE button to access your peak readings.

This will display the highest LEL, CO and H2S as well as the lowest O2 readings encountered while the instrument was in use.

To reset the peak readings, press and hold the AIR button until CLEAR RELEASE is displayed.

Press the POWER MODE button again to move to the STEL screen. STEL is a 15 minute average exposure for CO and H2S. Press POWER MODE again to move to the TWA screen. The TWA is an 8 hour average exposure for CO and H2S.

Press the POWER MODE button again to display the full scale readings of each channel.

Pressing the POWER MODE button again will get you back to the normal measuring screen.

RESETTING ALARMS
If the alarms are set up to latch, you can press and release POWER MODE to clear the alarms, if the unit is set up for self-resetting, the alarms will automatically reset once the environment has improved.

TURNING OFF THE GX-2009
Lastly, press and hold the POWER MODE button, TURN OFF will be displayed and the instrument will beep 3 times before shutting down.

We hope this video has helped you with your RKI GX-2009 operations. Please give JM Test Systems a call if you would like to rent or purchase RKI Instruments. We can also have your gas monitors serviced and calibrated if needed.
