5 FIELD CALIBRATIONS AND FLOW CHECKS
This section describes the audit and calibration process for the E-BAM flow system, ambient
temperature sensor, barometric pressure sensors, filter sensors, analog output, and span
membrane. The most important maintenance parameters are the leak checks, nozzle/vane
cleaning, and flow checks! The audit screens for the parameters described here are all found in
the FIELD CALIBRATION menu under the main E-BAM menu as shown below:

5.1 Leak Checks and Nozzle/Vane Cleaning
The E-BAM flow system must be checked for leaks before any flow calibrations are performed.
Scroll to the PUMP TEST line and press the MENU/SELECT key to enter the leak test and pump
test menu. The pump will turn on automatically when this screen is entered:
MODE:▼LEAK TEST
FLOW:
0.1 LPM
PRES: 732.3 mmHg
EXIT
The MODE parameter selects either the LEAK TEST or the PUMP TEST mode. The LEAK TEST
mode is used to check for flow leaks and to measure the leakage at the filter tape nozzle interface.
The PUMP TEST mode is used to test the capacity of the pump to determine when it needs to be
replaced.
