DataRAM 2000 Particulate Monitor Forest Service User's Guide

Configuring the Instrument at Your Office

First, remove the Swagelok protective cap from the air inlet on the top of the DataRAM. The DataRAM 2000 internal pump turns on at powerup and continues to run during setup. The Swagelok cap should be stored on the keeper pod on the back of the unit.

Push the 'ON' button on the front panel to power up the DataRAM.

Setting the Date and Time

The 'MAIN MENU 1' screen (figure 4) automatically displays at powerup.

Figure 4-The DataRAM’s main menu screen.

After pressing 'Next Screen' on 'MAIN MENU 1', 'MAIN MENU 2' will display.

Select 'Set Date, Time' by pressing the button beside that selection. The first digit on the hour will flash. Use the 'v' or '^' arrow buttons to change the numerals. Use the '>' or '<' arrow buttons to move across the date and time numerals. When the date and time are correct, press the 'EXIT' button to set them.

Zeroing the DataRAM

Press the 'EXIT' button once more or 'Last Screen' to return to 'MAIN MENU 1'.

With 'MAIN MENU 1' displayed, press the button next to 'Zero'. The DataRAM will perform a zero and span check to ensure that the optical device is clean. While the DataRAM is zeroing, the screen will flash 'ZEROING' and 'WAIT'.

Running the Span Check

After zeroing is complete, the DataRAM needs to perform a span check.

Press the button next to 'Span Check'. The following screen will display.

At the back of the instrument is a black 'Span Check' knob with arrows showing how to rotate it 'IN' or 'OUT'. While facing the screen, turn the 'Span Check' knob counterclockwise or 'IN' all the way until it stops. When the Span Check is complete, the screen will display 'RETRACT CALIBRATOR'. On the bottom of the screen, the 'Calibr Diff' should range between plus or minus 10%. If the 'Calibr Diff' is more than ±10%, repeat the 'Zero' and 'Span Check' again. If the value is still outside the ±10% range, contact MIE, Inc. or MTDC. Turn the 'Span Check' knob clockwise when facing the screen or 'OUT' all the way until it stops. When the Span Check is complete, 'MAIN MENU 1' will display.

Setting Parameters

Press the button beside 'Parameters'.

Press the button beside 'Next Screen' to display 'PARAMETERS 1' menu.

If the CalFactor is not set to 48 percent, press the button next to 'CalFactor'. Use '^' or 'v' to increase or decrease the number and '<' or '>' to move across the number.

• Set 'CalFactor' to 48 percent.
• Set 'Flowrate' to 2.0 Lpm.
• 'Auto Zero' and 'Alarm' can be set to 'OFF'.

If any parameters have been changed, press the 'EXIT' button to store the new settings. Press 'EXIT' one more time to go back to the 'PARAMETERS 1' screen.
