R6000S Operation Manual: Rev. G

g. Set backpressure regulator to 5 - 9 psi. (This pressure setpoint is not critical. The flow setting in

the next step is).

h. Adjust flow meter to 1.0.

Readjust backpressure regulator back to the pressure set in step 7E, if necessary.

Set Sample/Cal switch to Sample and Zero/Span switch to Zero.

k. Set Zero/Span switch to Zero.

Monitor flow meter for 1.0. If flow meter does not read 1.0, adjust regulator at cylinder.

m. Set Zero/Span switch to Span.

n. Monitor flow meter for 1.0. If flow meter does not read 1.0, adjust regulator at cylinder.

o. Set Sample /Cal switch to Sample and Zero/Span switch to Zero.

p. Adjust flow meter to 1.0.

q. Set backpressure regulator to the pressure set in step 7g.

NOTE: The sample/calibration system is now adjusted. When switching between sample and calibration

gases the flow meter and backpressure should maintain the same value.

Calibrating the Analyzer

NOTE: Ensure all gas supplies are turned ON and are at the correct flow and pressure settings and that

an adequate calibrating standard is available.

NOTE: Make sure the instrument has been running for at least thirty (30) minutes after all settings have

been achieved before making any adjustments.

3.2.1

1. Set sample/calibrate switch to calibrate; set zero/span switch to zero.

2. Verify Sample flow meter at 1.0.

NOTE: The sample flow meter will allow sample, span and zero gases to flow through when the

appropriate solenoids are switched/activated.

3. After detector output has stabilized for five minutes (shown by a consistent reading on the level meter

or an auxiliary recorder), press the auto zero button.

4. Once the auto zero light goes out, observe that the detector maintains 0.0 on the level meter or 4.0

mA on the current loop for two minutes.

Do not attempt to operate the analyzer until all installation procedures outlined

in the previous sections of this manual have been successfully completed.

Prior to normal operation, following heading, become familiar with the location

and use of all controls, indicators, connections, and accessories. Also,

carefully read all instructions and warning labels prior to operating any portion

of the system.
