Teledyne API – Model T700 Dynamic Dilution Calibrator Getting Started
73
Once installed and stabilized, generating a calibration gas from the T700 with a permeation
generator is the same as if the gas was being produced using a gas cylinder as the source, with the
following exceptions and note:
If you need a particular flow and don’t require a specific concentration then use
MANUAL mode. When generating in MANUAL mode the output concentration is
set by adjusting the DILUENT flow. The target and actual concentrations are
displayed as test values.
If you need a particular concentration but don’t require a specific flow then use
AUTO mode. When generating in AUTO mode the output concentration is set by
entering the desired concentration. The TOTAL flow entry has no effect; the
calibrator’s output flow depends on the target concentration. Again the target and
actual concentrations as well as the target and actual flows will be indicated as test
parameters.
Please note that the name for the permeation tube gas MUST be different than any
gas supplied to the calibrator from a bottle. For example if there is a H
2
S
permeation tube installed and a bottle of H
2
S gas connected to the calibrator, one
should be named H
2
S, while the second should be named something like H
2
S
2
.
The generator is shipped WITHOUT a permeation tube installed. The tube MUST be
removed during shipping or anytime that there is no diluent gas connected to the
calibrator since there must be a continuous purge flow across the tube. Permeation tubes
require 48 hours at 50C to reach a stable output. We recommend waiting this long
before any calibration checks, adjustments, or conclusions are reached about the
permeation tube. Once the T700 has stabilized, the response to the permeation tube is
not expected to change more than 5% if the zero air is provided for Teledyne API’s
M701 or other dry zero air source.
Teledyne API recommends that you purchase replacement permeation tubes from:
