5.2 PRESSURE ZERO SETTING
Only for PRU-353
Before you connect the pressure fitting to the PRU-353 you should set the zero
point of the pressure channel (channel 3). This setting should be made before
each recording run and compensates for changes in atmospheric pressure. With
the pressure port open to the atmosphere activate the bottom right switch ( 0).
After the zero has been set you can connect the pressure fitting to the port and
then pierce the container to let the pressure reach the sensor. The pressure port
(channel 3) is on the back edge of the instrument to the left of the display.
