Automatic Bump Testing and Calibration
The PC Controller Program will automatically perform a bump test or calibration on a
connected instrument if Auto Bump Test or Auto Calibration is selected in the
Configuration Window and if the bump test or calibration is due. The use of these
features allows the user to launch the PC Controller Program, turn on the EAGLE 2(s)
and walk away. No oversight of the bump test or calibration is needed. For this
reason, the calibration cylinders need to already be in place and the instrument
configurations must be such that the gas cylinders do not require any changing.
If Standard GAS is selected in the Configuration Window, only the standard 4 sensors
will be tested so only one calibration cylinder is needed. If All GAS is selected,
different GAS 2 configurations will need to be installed in separate manifolds with the
appropriate GAS 2 calibration cylinder connected to each manifold. EAGLE 2s with
more than one special sensor that require more than 2 gas cylinders cannot be bump
tested or calibrated automatically since those instruments will always need a gas
cylinder change during bump testing or calibration. The PC Controller Program will
only bump test or calibrate the standard 4 sensors if Auto Bump Test or Auto Cal is
selected. Even if you have a 5-gas mix that contains the target gases for the standard
4 sensors and one of your special sensors, you cannot bump test or calibrate all
installed sensors using the automatic bump test or automatic calibration features.
The processes do not give you the opportunity to use the 5-gas cylinder. If you have
instruments with more than one special sensor, RKI Instruments, Inc. recommends
manually bump testing or calibrating that instrument with the PC Controller Program
as described in “Bump Testing an Instrument with Special Sensors” on page 71 and
“Calibrating an Instrument with Special Sensors” on page 87.
To automatically bump test or calibrate an instrument or instruments:
1. Be sure that Auto Bump Test or Auto Calibration are selected in the
Configuration Window. See “Setting Up the PC Controller Program” on
page 30 for instructions.
2. Verify that all of the bump test and/or calibration parameters are set correctly.
See “Setting Up the Configuration” on page 30 for instructions.
3. Verify that the appropriate calibration gas cylinder or cylinders is connected to
the appropriate manifold line.
4. Ensure that the gas out to EAGLE 2 line is connected to the inlet of the EAGLE
2.
5. Establish a connection between the SDM-E2, EAGLE 2 and the PC Controller
program as described in “Connecting Instruments to the PC Controller
Program” on page 40.
6. The bump test or calibration will begin 1 minute after the last connected
EAGLE 2’s instrument information download is complete.
7. During an automatic bump test, if the bump test fails, a calibration is
immediately performed.
8. If Auto Bump Test and Auto Calibration are both selected, the calibration will
begin 1 minute after the bump test has finished.
