If it does not match the gas concentration in the cylinder(s), change the auto calibration value for that channel. See “Sensor Tab” on page 165 for instructions. When using a 3-gas (no H2S channel) or a 4-gas (H2S channel included) cylinder, to calibrate a standard instrument, select all channels.
8. You will then be asked to confirm the auto calibration values and the instruments that the calibration cylinder will be used for. Be sure the auto calibration values match the values listed on the calibration cylinder. The serial number and gas combination of all selected instruments will appear sequentially beneath the gas cylinder concentration. If you are calibrating a standard 4-gas GX-2012 or GX-2012s, the screen will appear as shown below. All channels will be calibrated using GAS 1.
If you are calibrating a standard 4-gas plus %volume GX-2012 or GX-2012s, the screen will appear as shown below. The standard 4 sensors will be calibrated using GAS 1 and the %volume sensor(s) will be calibrated using GAS 2. The GAS 2 selection box is deselected by default. You must select the GAS 2 box if you wish to calibrate the %volume sensor. If you do not wish to calibrate the %volume sensor, leave the GAS 2 box deselected.
10. The pump(s) will start and the program will indicate that air is flowing. The CAL S LED will begin to flash amber. Air will be applied to the instrument(s) for 45 seconds, then the PC Controller Program will perform a zero adjustment on all the channels. If at any point during the calibration you wish to cancel the calibration, click the Cancel button in the lower right corner of the screen. The calibration will be aborted and the CAL S LED will turn solid amber.
11. After air is applied, and if all the channels passed the zero adjustment, calibration gas will be applied. The GAS 1 indicator on the program screen will come on.

Appendix A: Multiple Instrument Configurations RKI Instruments, Inc. recommends bump testing and calibrating GX-2012s and Gas Tracers separately. If desired or needed, however, GX-2012s and Gas Tracers can be bump tested and calibrated at the same time using the PC Controller Program. If you are going to test the instruments together, do not manifold the different types of instruments together.
the Configuration” on page 32 for instructions. 3. NOTE: 4. Verify that the appropriate calibration gas cylinder(s) are connected to the appropriate SDM-2012(s) or manifold line(s). The ppm sensor will be bump tested first. Be sure that a 6 inch humidifier tube is used to connect the ppm calibration cylinder to the GAS 2 fitting on the back of any SDM-2012(s) with Gas Tracers installed.
5. Select the instruments you wish to bump test and click on them to highlight them as shown below. To select multiple instruments for bump testing, hold down the Control button on the keyboard as you click them. Figure 141: Instrument Selection 6. If you would like an automatic calibration to occur after a failed bump test, select the Force Calibration selection box. 7. Click the Bump test button in the lower right corner of the main program window.
8. You will be asked to confirm which instrument channels will use GAS 1 for the bump test. The gas concentration shown next to each channel is the auto calibration value for that channel. If it does not match the gas concentration in the cylinder(s), change the auto calibration value for that channel. See “Sensor Tab” on page 165 for instructions. If you are bump testing standard GX-2012s and standard Gas Tracers, leave the first channel (the ppm sensor) deselected and select all other channels.
If you are bump testing a 0 - 10000 ppm range Gas Tracer, the Gas Cylinder Confirmation Screen will appear as shown below. Even though there are no other sensors installed in the instrument, GAS 2 will still be used to bump test the ppm sensor. The ppm sensor will be deselected in this screen and cannot be selected. Figure 143: Gas Cylinder Confirmation Screen, 0 - 10000 ppm Gas Tracer When all of the desired channels are selected, click OK.
the ppm combustible sensor, leave the GAS 2 box deselected. The SDM-2012 will bump test the ppm sensor using the Gas Tracer’s WET setting for the fresh air adjustment and the span adjustment. This is not user adjustable using the PC Controller Program. If the SDM-2012 is not in a fresh air environment, a zero air cylinder must be used with a 6 inch humidifier tube connecting the cylinder to the AIR fitting.
If you are bump testing any instruments that include a %volume sensor, the screen will appear as shown below and will indicate a gas cylinder change is needed. The ppm sensor will be bump tested first with GAS 2. The standard sensors will then be bump tested using GAS 1. The %volume sensor will then be bump tested with GAS 2. The user must change the GAS 2 cylinder before the %volume sensor can be bump tested. The GAS 2 selection boxes are deselected by default.
If you are bump testing a 0 - 10000 ppm Gas Tracer, the screen will appear as shown below. The ppm sensor will be bump tested using GAS 2. The GAS 2 selection box is deselected by default. You must select the GAS 2 box to bump test the ppm combustible sensor. If you do not select the GAS 2 box, the bump test will not continue. Be sure that the ppm calibration cylinder is connected to the GAS 2 fitting with a 6 inch humidifier at the start of the bump test.
11. If a bump test or calibration has already been performed by the PC Controller program on a GX-2012 or a Gas Tracer with a %volume sensor installed, the docking station will perform a purge before beginning the bump test. The purge ensures that any %volume calibration gas does not come in contact with the ppm sensor and affect its readings. The screen will indicate that you need to remove the gas cylinder from the GAS 2 fitting on the back of the SDM2012.
15. The pumps will start and the program will indicate that air is flowing. The AIR indicator on the program screen will be on. The BUMP T LED on the SDM2012 control panel will be flashing amber. Air will be applied to the ppm sensor for 45 seconds, then the PC Controller Program will perform a zero adjustment on the ppm channel. If at any point during the bump test you wish to cancel the bump test, click the Cancel button in the lower right corner of the screen.
16. After air is applied, and if the ppm sensor passed the zero adjustment, calibration gas from the GAS 2 cylinder will be applied to the ppm sensor. The GAS 2 indicator on the program screen will come on and calibration gas will be applied to the ppm sensor for the duration specified in the Gas Exposure Time parameter in the Configuration Window. Figure 148: GAS 2 PPM Gas Flowing The PC Controller program will analyze the results.
17. After calibration gas has been applied to the ppm sensor, fresh air will be applied to the standard sensors (catalytic LEL, O2, H2S (GX-2012 only), and CO) and the %volume sensor (if installed) for 45 seconds and the PC Controller program will perform a zero adjustment. Figure 149: Air Flowing to Standard Sensors The PC Controller Program will analyze the zero adjustment results.
18. After air is applied, and if all standard channels and the %volume channel (if installed) passed the zero adjustment, calibration gas from the GAS 1 cylinder will be applied. The GAS 1 indicator on the program screen will come on and calibration gas will be applied to the instrument(s) for the duration specified in the Gas Exposure Time parameter in the Configuration Window. Figure 150: GAS 1 Flowing The PC Controller Program will analyze the results.
