the four screws and take off the box cover. Inside the enclosure there are a set of fi ve plug-in
circuit boards, and one other board mounted behind and at right angles to the others.
4. Carefully remove the left most plug-in circuit card and replace it with the Model 80 calibration
fi xture card. The card to be removed should be marked 8.X near the front. Insert the Model
80 calibration fi xture with the component side of the board facing to the left. Connect the
cable that was furnished with the Model 80 to the jack in the top of the fi xture and to the
EXTERNAL INPUT jack on the back of the Flo-Lab.

7. Use the POSITION knob on the front panel of the Flo-Lab to move the red cursor position to
the 1st division from the bottom of the display. Turn the SIZE control clockwise until the signal
is maximized. Both channels should display an 8 division signal, plus or minus 10%.
8. Press the 5mm / S button to run the chart recorder. The signal on the chart should be 32 mm
plus or minus 3 mm in amplitude.
9. Press STOP to stop the chart recorder. Press the MENU button to advance to “5 - EXTERNAL

10. On the left side of the Flo-Lab front panel, use the POSITION control to center the trace in the
grid on the computer monitor. Turn the Flo-Lab SIZE control counter-clockwise to set SIZE A
and SIZE B both to 85.
11. Start the chart recorder at 5mm / S, then set the switches on the Model 80 calibration fi xture
to “A” and “ON”. After 2 or 3 seconds, set the Model 80 to “B”. Verify that, with the switch on
the Model 80 in position “A”, 5 green LEDs under TOWARD are on; and that in position “B”,
5 red LEDs under AWAY are on. Switch back and forth from “A” to “B” several times, then
STOP the chart recorder to examine it. Press The ( key to “freeze” the trace on the computer
monitor.
12. The upper trace on the monitor will look like a square wave, 8 divisions in amplitude, the lower
trace will be 4 divisions.
