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 avail able 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.
INTERFACE MODEL 9840 VER 6.0.2 RUN MODE The Model 9840 has three modes of operati on, Run mode, Setup mode, and System Calibration mode. At power-on it will be in Run mode. The first line of the display show an item label (Load A), a value (0.0000), and a unit label (Lb).
INTERFACE MODEL 9840 VER 6.0.2 The table below summarizes the options. Whether the user sees torque or load for each channel depends upon the cell type that was calibrated or selected for that channel. Load A/B Pounds, Kilograms, Newtons, PSI, MegaPascals, Kilo-Pounds, Kilo-Newtons, Metric Tons, mV/V, grams.
INTERFACE MODEL 9840 VER 6.0.2 The load or torque is always reset to zero. A single channel unit will automatically set Load A or Torque A to zero. Reset Button The Reset button brings up a list of th.
INTERFACE MODEL 9840 VER 6.0.2 Print Button If the Print option is purchased, the Print Button can be used to either print data or to freeze the display. If the Hold option is purchased, the functionality of the button is set using the System Setup options.
INTERFACE MODEL 9840 VER 6.0.2 SETUP MODE SUMMAR Y The table below summarizes the setup mode menus. Detailed information about each individual item is presented in the following sections.
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).
INTERFACE MODEL 9840 VER 6.0.2 Entering Numerical Dat a 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.
INTERFACE MODEL 9840 VER 6.0.2 1. Source: -- This entry allows you to scroll through a list (using the left/right or plus/minus buttons) to select the source of the data that will drive the analog output. The standard list will include load or torque, peak, valley, gross, position, and velocity.

INTERFACE MODEL 9840 VER 6.0.2 >>Cal Check Selecting this item will run a calibration check on the cell attached to Channel A or B. The Model 9840 will measure the shunt value of the cell and compare it to the shunt value that was recorded when the cell was last calibrated.
INTERFACE MODEL 9840 VER 6.0.2 set the torque. When the Model 9840 is reading the cell it will display the “Reading...” message for about 10 seconds. During this time it is important that the masses or torque are not disturbed since all the readings taken are averaged together to obtain the calibration data.
INTERFACE MODEL 9840 VER 6.0.2 7. Trip if source < / > Set -- Choosing source>set means that the limit will be activated when the source becomes larger than the set point. Choosing source<set means the limit will be activated when the source becomes less than the set point.
INTERFACE MODEL 9840 VER 6.0.2 >>Com Address This item allows you to set the address of this unit used for the RS232 ASCII command set. Valid values are 1 through 254. If the RS232 multi-drop option is installed you must be sure that all the attached units have different addresses to prevent data collisions.
