The internal calibrator is designed to generate a calibration gas of up to 8 PPM.
TBE recommends calibrating with a span gas of at least 80 PPB on the 100 PPB
range. Calibrating the analyzer with low PPB oxygen generated by the internal
calibrator may require up to 2 hours to stabilize. However, calibration at
500–700 PPB may be completed within 20–30 minutes. The recovery to zero
line after calibration at 500–700 PPB is slower than that with 80 PPB, but this
slow recovery easily offsets the longer span stabilization at 80 PPB. Therefore,
it is highly recommended that you calibrate the analyzer at 500–700 PPB when
using the internal calibrator to achieve the maximum accuracy.

When you press

ACK

, the screen indi-

cates that the system is purging the
calibrator and displays the message:

PLEASE

WAIT

...

Do not press

SKIP

before the purge is

completed if fresh electrolyte has been
added to the calibrator. Otherwise, you
may press

SKIP

after a 2 minute purge.

6.

The system automatically begins a 5-
minute purge of the calibration line. The
screen displays the time remaining until
the process is complete and displays the
message

PLEASE

WAIT

...

7.

After purging, the screen displays the
present oxygen content and flow rate,
and directs you to check the flow rate.
Press

ACK

to continue, or

ESC

to return

to previous menu.

8.

The screen displays the present oxygen
content and the flow rate. Use the

UP

and

DOWN

buttons to choose the

required calibration gas concentration.
When the oxygen level has stabilized,
press
