Getting Started M703E Calibrator Operator’s Manual
3.4.7. SETTING THE M703E’S OUTPUT FLOW RATE
The output flow rate of the M703E should be adjusted to match the gas flow requirements of the analyzers
connected to the output manifold.
NOTE
The minimum total flow should equal the sum of the flow requirements of all of the instruments to
which the M703E will be supplying calibration gas plus 1 LPM excess flow.
Example: If the M703E is will be expected to supply calibration gas mixtures simultaneously to two
analyzers each requiring 0.8 LPM , the proper Total Flow output should be set at a minimum of:
(0.8 + 0.8) + 1.0= 2.6 LPM
To set the output flow:
1. Open the front panel of the calibrator down by releasing the two snap-in fasteners at the top of the front
panel.
2. Pull out the regulator knob and adjust the regulator until the desired flow is achieved.
The front panel of the M703E displays the approximate output flow based on the measured regulator
pressure, but this flow should be verified with an independent calibrated flow meter attached to the
on of the CAL GAS outlets on the back of the instrument (see Figure 3-2).
3. Push the reg
ulator knob back in to lock.
4. Close the front panel.
