1. Shut off the process gas supply valve(s) upstream of the PC100 Series.
If such a valve is not available, shut the valve on the gas panel. Tag the
valve at this point to prevent accidental re-exposure of the process gas
to the gas line.
2. Cycle purge the gas line with dry nitrogen or argon to fully flush out the
process gas. Cycle purging consists of evacuating to a low pressure
adequate to induce out-gassing and then purging to remove adhered
moisture and oxygen. If a toxic or reactive gas is present and a clogged
PC100 Series is suspected, then proceed with caution. Pump down
and purge the PC100 Series from both downstream and upstream
lines. If check valves are present in the gas line, both pumping down
and purging are required. Pumping down without purging is inadequate.
If a good vacuum source is not available, the PC100 Series can be de-
contaminated by purge only.
3. Repeat the purge cycle several times within 2-4 hours to complete the
cleaning. For toxic and corrosive gasses, it is recommended to use
100-120 cycles.

2-12 Position and Mount the PC100 Series
Position the PC100 Series so that the gas flow is pointed in the direction of
the flow arrow on the PC100 Series rear S/N label. The various mounting
positions for UPSTREAM applications are described in Figure 2-2, and the
mounting positions for DOWNSTREAM applications are described in
Figure 2-3.
The standard orientation for the PC100 Series is Horizontal Base Down (HBD).
The PC100 Series is configured with ¼" VCR fittings, secure the PC100
Series block to the gas panel with two, 8-32-UNC-2B" screws. Then
connect the inlet/ outlet fittings to the gas supply line using two
wrenches. Tighten the fittings to manufacturer recommendations.

2-13 Perform a Leak Test
It is critical to leak test the gas supply lines and PC100 Series connections
before turning on the process gas supply after any new installation. Check
for leaks using a helium leak detector or any other appropriate leak test
method. Follow leak test specifications as defined by integrator.
2-14 Zeroing the PC100 Series - Setup
The PC100 Series pressure transducer and flow meter zeroing process is
performed from the backlight LCD display on top of the PC100 Series.
OEM tools using a microprocessor or computer for operating the PC100
Series should sequence the PC100 Series off between processes. To
accomplish this, simply provide a zero set point. The PC100 Series will
shut off automatically.
Shut-off valves, whether upstream or downstream from the PC100 Series,
should be programmed to turn on before the PC100 Series is turned on
and turned off after the PC100 Series is turned off.
The following steps are required before the PC100 Series is zeroed.
1. Make sure that the PC100 Series has been installed inside the
equipment (panel) for at least four hours and powered up at least one
hour prior to zeroing. This insures that the PC100 Series is in its "use
attitude" and is operating at normal temperature. If the PC100 Series is
subjected to a vacuum purge for more than one minute, turn off the
PC100 Series (ie., provide a zero setpoint) for a time period of twice the
vacuum purge time.
2. Read the output signal of the PC100 Series. This output signal is the
initial flow in percent of full scale. The output signal should be 0.0 (±
0.1%). If the output signal is too high, re-zero the PC100 Series as
described below.
2-14-1 Zeroing the PC100 Series Pressure Transducer from the LCD Display Panel (PC115 & PC125)
1. Place the PC100 Series under a strong vacuum with the PC100
Series set to 100% set point. Make sure that upstream valve is
closed and the downstream valve is open. Allow time for the
upstream pressure to bleed off.
