safely dispersed, such as an open window.
CAUTION:
The maximum recommended length for the exhaust tube is 30 feet. Do
not use more than 30 feet of tubing or tubing with an ID of less than
3/16 inch for the exhaust tube or the bump test and calibration
accuracy may be adversely affected. The tube that is shipped with the
SDM-E2 has an ID of 3/16 inch and is 10 feet long.
6. Install the 3 foot long 3/16 inch ID tubes that are included with the SDM-E2 on
the GAS 1 and GAS 2 fittings.
Setting the Operational Parameters
in Edit Mode
Once the hardware has been assembled, use Edit Mode to confirm or adjust bump
test, calibration, and gas inlet parameters before using the SDM-E2.
The bump test parameters define how long fresh air and calibration gas are applied to
an instrument during a bump test. They also define the tolerance used in determining
whether an instrument fails or passes a bump test and whether or not a calibration
automatically takes place if a bump test fails. The calibration parameters define how
long fresh air and calibration gas are applied to an instrument during a calibration.
The gas inlet parameters define what gas inlet fittings (GAS 1, GAS 2, or both) will be
used during bump tests and calibrations.
The bump test and calibration parameters are saved in the SDM-E2’s memory. If a
parameter is changed with one particular EAGLE 2 installed in the SDM-E2, the
change will be in effect for the bump test or calibration of any subsequent EAGLE 2
until the parameter is changed again.
Bump Test & Calibration Parameters
There are four bump test parameters and two calibration parameters. The two
calibration parameters, air sample time and calibration gas sample time, are also
bump test parameters. The parameters are described below. Table 3 below shows
the factory settings for the bump test and calibration parameters. If you wish to use
the factory settings, then you do not need to make any parameter adjustments. If you
wish to confirm or change the parameter settings, follow the instructions below in
“Setting the Bump Test Parameters” on page 18 or “Setting the Calibration
Parameters” on page 20.
