2-8
Shut-off valves, whether upstream or downstream from the GF100 Series,
should be programmed to turn on before the GF100 Series is turned on
and turned off after the GF100 Series is turned off.
1. Place the GF100 Series under a strong vacuum with the GF100
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.
2. Looking at the top of the GF100 Series, press the "Display" button,
starting at the MACID, four times to "PSI" or five times to "kPa" or until
the LCD displays the labels "PSI" or "kPa". The GF100 Series will
display pressure in units of PSIA or kPa. Press and hold down the Zero
button a minimum of 5 seconds or until the display reads 0.000, with
the last two digits flickering at different values. The pressure transducer
zeroing procedure can be done while the display is either in PSIA or
kPA output. Refer to Figure 2-6.

After completion of the pressure transducer zeroing, the LCD display will
read 0.0 with the last two digits flickering as shown in Figure 2-7.
