3 Operation

3.1 Power Up

Pull the protective caps from the flow module ports before powering

up. Do not apply pressure to the flow module at power up (this

ensures accurate low-pressure transducer zero calibration).

Press the I/O (on/off) key on the controller module to power up the

Certifier

FA Test System (the controller module powers all of the

attached Certifier

FA Test System components). At power up, the

controller module shows information in this sequence:

1. All LCD segments light (about two seconds).

NOTE: If battery voltage is below the minimum operating level,

the battery symbol lights and the controller module will turn off.

2. Firmware revision shown (about two seconds).

3. Controller module verifies connection and correct operation of the

flow module and oxygen sensor (if installed). If the oxygen

sensor is installed, the controller module will display a

symbol.

4. Default measurements displayed:

High Flow module: flow (top line), low pressure (bottom line).

Low Flow module: flow (top line), respiratory rate (bottom line).

CAUTION

 To ensure accurate measurements, wait about one minute for the

Certifier

FA Test System to warm up. If environmental conditions

have changed significantly, more time may be necessary.

 To avoid damage to the Certifier

FA Test System components,

always use bacteria filters upstream of the flow modules, and

always cap flow module ports when not in use.

 If liquid has penetrated any of its components, do not use, and

return to the factory for calibration.

The test system conserves battery life by automatically turning off if

none of the keys are pressed for 15 minutes. To override the

automatic turn off, press the GAS SELECT key with the I/O key when

turning on. The will appear while the software revision is

displayed during power up if the automatic turn off is disabled.
