INTERFACE MODEL 9840 VER 6.0.2 QUICK START This section will help you get your Model 9840 set up and operating in just a couple of minutes. The back panel is shown below. You will need to make at least two connections here. First be sure that the power switch is off (the lower part of the rocker should be pressed in). Connect the AC power line and plug it in. MODEL 9840 BACK PANEL Next connect a load or torque cell to the 9 pin female connector labeled “Load A”. You should u

INTERFACE MODEL 9840 VER 6.0.2 The rightmost button will change the units that are being used. Repeated presses of this button will cycle through the list of units available for the currently displayed item. For example, with Load A showing you would see Lb, kg, N, PSI, MPa, Klb, kN, t, mV/V, grams, and then back to Lb. With Torq A, you will see LbI, NM, OzI, and mV/V. Switching from a load to a torque cell and back will automatically reset Analog, Limit, and Filter Window settings to

INTERFACE MODEL 9840 VER 6.0.2 SETUP MODE Setup mode is used to change the setup of the Model 9840. To enter setup mode press the two end buttons at the same time ( “<“ and “>“ ). The row of four buttons will now function as indicated by the lower set of labels (Plus, Minus, Enter, and Escape). If the optional keylock is in the locked position you will see “>Setup is Locked” when you try to enter setup mode. This prevents accidental or unauthorized changes to the setup of the unit.

INTERFACE MODEL 9840 VER 6.0.2 Entering Numerical Data At times you will need to enter numerical data into the Model 9840. The method is consistent in all cases. A number is presented on the left side of the display with an underline cursor. • Left ( “<“ ) moves the cursor left one position. If you are on the leftmost digit a new zero will be added. Thus 10.000 will become 010.00 where the cursor has moved from the tens place to the hundreds place. • Right ( “>“ ) moves the cur
