INTERFACE MODEL 9840 VER 6.0.2
INTRODUCTION
The Model 9840 is a CE compliant and versatile precision instrument intended for the
digital readout of strain gage sensors such as load cells and torque cells. Optical
encoders are also supported.
Here is a quick listing of its features:
• Full bi-polar 6 digit display (±999,999) using two line, 20 character, vacuum
fluorescent display for clear, precise indication of measured quantities and limit status.
• No knobs or dials. No internal jumpers. All adjustment and calibration is done using
user-friendly front panel menus. Keylock option to prevent accidental or unauthorized
changes to the unit’s setup.
• Measure load and gross weight in pounds, kilograms, Newtons, PSI, MegaPascals,
kilo-pounds, kilo-Newtons, metric tons, mV/V, or grams. User defined base area for
PSI and MPa. Tare at any time. The sum of the loads on both channels is also
availabe.
• Measure torque and gross torque in Pound-Inches, Newton-Meters, Ounce-Inches,
or mV/V. Tare at any time. The sum of the torques on both channels is also availabe.
• Capture the load peak and valley, display in pounds, kilograms, Newtons, PSI,
MegaPascals, kilo-pounds, kilo-Newtons, metric tons, mV/V, or grams. Reset at any
time.
• Capture the torque peak and valley, display in in Pound-Inches, Newton-Meters,
Ounce-Inches, or mV/V. Reset at any time.
• Measure position and velocity with optional encoder input. Display in English units,
metric units, or in percent of a user defined base length. Reset at any time.
• Four contact closure Limit switches. You can set which signal drives the limit (load,
torque, peak, valley, position, or velocity), normally open / normally closed, set point,
and manual reset (latched) or automatic reset (not latched).
• Print current readings of load, torque, peak, valley, position, and velocity using the
currently selected units at the touch of one button (optional).
• Automatic identification of calibrated cells with auto-id option.
• Calibration for cells using manufacturer’s milli-volt per volt calibration factor, 6 point
mass and milli-volt per volt, 2 or 5 point known mass, 6 point torque and milli-volt per
volt, 2 or 5 point known torque, or internal precision shunt calibration. A back panel
switch allows you to choose between two values used for the shunt calibration so
there is no need to open the unit.
• Analog output of any signal (load, torque, peak, valley, position, velocity) with user
defined scale factor and offset. Large, buffered ± 10.00 volt output.
