Instructions for measuring pressure in the LI-610.
- Press the green button to turn the 610-03 on. A low battery is indicated by a "BAT" message in the lower left hand corner of the display. Slight fluctuations may occur on the display if the two ports on the top of the 610-03 are open.
- Select the range of the instrument by pressing either the "1" or "0.1" buttons. Pressing the "1" button selects a range of 0-1000 mbars (1 mbar resolution), and the "0.1" button selects a range of 0 to 199.9 mbars (0.1 mbar resolution).
- Connect a section of the 1/8" ID tubing (included) between the fill/drain port on the LI-610 condenser block housing and the left-hand pressure connection port on the top of the 610-03. The display will show positive values if pressure is exerted on the left port, or if a vacuum is applied to the right port. The display will show negative values if a vacuum is applied to the left port, or pressure is exerted on the right port.
- With the LI-610 turned OFF, zero the 610-03 by turning the knob on the bottom of the manometer in either direction until the display reads 000 (or 00.0).
- The millivolt output connector is located between the two pressure ports on the top of the 610-03. The voltage output from the 610-03 is linear, and corresponds to 1 millivolt/1 millibar. Connect the red lead to the positive terminal of your input device, and the black lead to the ground (or chassis ground, if available).
- Press the red button to turn the 610-03 off.
Note: Velcro is included to attach the 610-03 to the LI-610, if desired. Do not attach the velcro to the battery compartment panel on the back of the 610-03, as repeated detachment can damage the panel.
