Current Manifold Pressure – Current manifold pressure in psia.
Stored Ambient Pressure – Stored ambient pressure in psia.
Pressure Difference – The difference between the current manifold pressure and the stored ambient
pressure.
Fault Code – Current fault code (see page 14).
Purge Valve Asterisk (∗) – The purge valve can be opened and closed by pressing the Keypad Left
button. An asterisk appears on the display when the purge valve is open causing the monitor to draw
air from the purge-air bag.

2.16 Print/Plot Logged Gas Levels

A printout or plot of the last 200 ppm measurements can be made by connecting the optional Bacharach
printer and printer cable to the monitor as follows. (Refer to Replacement Parts on page 23 for printer
and cable part numbers).
1. For a printout or plot to be made, the monitor must have been set up to record gas
measurements using the LOG INT function.
2. Interconnect the RS-232 connectors located on the printer and monitor.
3. If not already done, refer to the printer manual and set the printer's communication parameters to:
•
Data bit = 8
•
Parity = None
•
Baud rate = 19200
•
Handshaking = DTR
4. From the Data Display screen, press both the Keypad Left and
Right buttons at the same time to display the first Function Menu
screen. Next, use the Keypad buttons to move the arrow (>) until
it points to either PRINT to produce a printout, or PLOT to
generate a plot.
5. Press ENTER to start the print/plot process.
