Description
The Model 9860 is a TEDS IEEE 1451.4 compliant, enhanced performance, microprocessor-based indicator
capable of interfacing directly to a low level strain gage load cell transducer. The 9860 provides (3) user
selectable calibration modes and (1) factory calibration mode. Consult Interface before accessing the
factory calibration mode.
1. CAL1:Manual entry of zero and calibration values using a live or simulated transducer input.
2. CAL2: Allows calibration to a specific non-TEDS transducer, when the MAXIMUM FORCE and
MAXIMUM ELECTRICAL values (mV/V), of that specific transducer are known.
3. TEDS: The 9860 automatically calibrates itself, when power is applied, if connected to a TEDS
transducer. It must first sense a TEDS connection and then successfully read the TEDS template
#33 data stored in a one-wire DS2344 or similar microchip on a configured transducer. This
calibration mode overrides any previously stored calibration.
An internal, high gain, fully-differential amplifier and a 16-bit analog-to-digital converter combine to
accurately digitize the input signal. This signal is filtered by a 1kHz analog filter. An additional, smart
digital filter, with user selectable sample size and filter window (band), allows optimization for specific
operating conditions, trading off depth of filtering and step change tracking. Unique, dual auto-calibrated
±10Vdc and 4-20mA real time analog outputs are standard. A RS232 interface provides facilities to
continuously read data communicate command and query operating modes and parameters. A powerful 8-
bit microprocessor utilizes a Real Time Operating System (RTOS) to provide seamless control of display,
communications and mathematical computations.
A TEDS status indicator provides the information on the TEDS configuration of the input. See table for
TEDS indicator description.
A precision 10Vdc @ 120mA, short circuit protected, transducer excitation supply is also provided.
A front panel RCAL switch provides a convenient feature for checking calibration. TARE and CALIBRATION
are easily performed via front panel pushbuttons.

Open Collector Set point Outputs
The Interface model 9860 load cell indicator is equipped with open collector set point outputs. Open
collector outputs work somewhat like dry relay contacts except that they only allow current to flow in
one direction. The beauty of open collector outputs is, since these outputs are floating, they can be used
with any voltage source up to 50 VDC. In this way you can match the output voltage level of the 9860 to
any external equipment input be it 2.5 VDC or 48 VDC.
See Appendix H for further details.
Input range and analog output adjustment settings
The 9860 has selectable 2.5 and 5mV/V transducer inputs. See appendix E for further details.

While in the Mode Selection sequence, the indicator is no longer monitoring the input signal. To exit
Depress MODE once to save any changed settings, and then RESET to return to normal operation.
Decrement or Tare Switch
This switch serves two functions, depending on the present status of MODE. If the meter is in the Mode
Selection sequence, this switch decrements the flashing digit.
If the meter is in its normal operating mode, it becomes the TARE switch. Depressing TARE will
automatically zero the readout, illuminate the TARE LED and zero the analog output. Depressing and
holding TARE depressed for approximately 3 seconds will UNTARE the readout and extinguish the TARE

LED. TARING is accomplished by storing the reading prior to TARING and subtracting this value from all
subsequent readings.
Increment or Cal Switch
This switch also serves two functions, depending on the present status of MODE. If the instrument is in the
Mode Selection sequence, this switch functions in the following manner.
1.In the CAL selection mode, it selects the calibration mode: CAL OFF, CAL1 or CAL2.
2.In the parameter update mode, it will increment the flashing digit or toggle status.
If the instrument is in its operating mode and waiting for a CAL1 calibration to be performed this switch
will input zero and calibration values. Be sure to read Appendix B & C before using this switch.
Step Switch
When the instrument is in the Mode Selection sequence, this switch allows the user to cycle through the
digits. Used In conjunction with and it allows rapid updating of numerical values.
Display Switch
In operating mode this switch cycles the readout to display:
Annunciator(s) Illuminated
Peak-Valley PK and VAL
Peak PK
Valley VAL
Instantaneous readings None
While in the Peal-Valley, Peak or Valley readout mode, the RESET switch resets the readout to the
instantaneous value. In the Peak-Valley readout mode, resets both Peak and Valley readouts to the
instantaneous value.
Reset or Exit Switch
This switch also serves two functions, depending on the present status of MODE. If the instrument is in the
Mode selection sequence, this switch is used to Exit this sequence and return to the normal display mode.
Any selections made during the Mode Selection sequence, prior to that selected just before exiting, will
be saved and remembered in non-volatile memory.
If the instrument is in the normal (instantaneous) display mode the
reset switch will reset the stored Peak, Valley and Peak-Valley
readings to the current Instantaneous value.
RCAL Switch
This switch activates a reed relay, which places a fixed resistor
across -Sig and -Vexc for a positive RCAL reading, or across -Sig and
+Vexc for a negative RCAL reading. Removing the back panel of the
instrument case will allow access to the RCAL resistor and settings
jumper. The jumper on P2 determines the polarity of the RCAL
output with position 1 for negative and position 2 for positive. The
RCAL resistor can be changed if desired; a 10ppm tempco resistor is
recommended.

Menu Function Definitions
Filter Value (FILtEr) (00 to 99)
The 9860 uses a filter based on a digital averaging technique where N samples are arithmetically
averaged.
Subsequent averages subtract the oldest reading and add the newest reading. The number of readings is
equal to the value of (FILtEr). The default filter setting is 99.
Higher (FILtEr) values produce stronger filtering with a slower response. Maximum Filtering=99.
Filter Band (bAnd) (001 to 999)
To permit a heavy filter and still have fast response to a step input change, the filter operates only inside
a stable Band. If two consecutive conversions have a difference greater than the bAnd value, the
instrument temporarily shuts off the filter, permitting maximum response. When the difference is again
within the bAnd value, the filter returns to the selected (FILtEr) value. The bAndnumber corresponds
roughly to the raw ADC counts. The factory default is bAnd = 999. See appendix A for filter details.
Decimal Point (dP) (x.xxxx, xx.xxx, xxx.xx, xxxx.x, xxxxx)
dP allows selection of decimal point locations for display. The locations selectable are shown in ( ) above.
The Increment and Decrement switches are used to shift decimal places.
Calibration Number (CAL) (00001 to 99,999)
In the ON1 mode, the (CAL) is equal to the desired reading corresponding to the calibration load, whether
the load is Actual, simulated or from RCAL. This value is in user units (lbf or N for example). The number
is entered prior to performing the calibration. A Full Scale Number must also be entered to scale the
ANALOG output. See ANALOG OUPUTS for a detailed description.
In the ON2 mode, (CAL) is equal to the FULL SCALE value of the transducer. The full scale value will be
Automatically set to the Calibration Number.
In the TEDS mode, the (CAL) value is automatically set, by the instrument, to the (FS) value read from the
Transducer. See CALIBRATION INSTRUCTIONS for more details.
Scale
In the calibration ON2 mode, the SCALE value is equal to the transducer MAXIMUM OUTPUT value in mV/V
as found on a calibration certificate. In this mode values are entered manually similar to what would be
automatically uploaded from a TEDS transducer. SCALE is only changeable in the ON2 mode.
Full Scale Number (FS) (00001- to +/-99999)
The (FS) represents the value at which the ANALOG output is at full value (10v or 20mA). In the ON1
calibration mode this value can be altered to fit the needs of the user. For example if using a 10000lbf
load cell but the user is only interested in the output up to 5000lbf the FS can be set for 5000 for a 10V
output at 5000lbf. The display would still read values up to and over 10000lbf. This allows for a higher
analog output resolution (lower noise) over a smaller input range of interest.
In the ON2 mode, the (FS) value is equal to the user entered CAL value. (FS) is automatically updated
when the CAL value is updated. It cannot be altered by the user.
In the TEDS mode, (FS) is used to indicate the full scale value of a TEDS transducer. (FS) cannot be
changed in this mode.

Setpoint xto Monitor
This function allows Setpoints 1-4 to monitor the instantaneous, peak, valley, or peak minus valley
displays. The Increment or Decrement switches are used to cycle through the various displays. To signify
which display is being monitored, the least Significant 7-segment display will be illuminated as shown
below.
Setpoint xto be (SPxHI) {SPxHI, SPxLO}
This allows Setpoints 1-4 to be a High or Low Setpoint. The Increment or Decrement switches are used to
cycle through the HI or LO selection.
A High Setpoint is disabled when the compared value is less than the Setpoint value. The High Setpoint is
enabled when the compared value is equal to or greater than the Setpoint value.
A Low Setpoint is disabled when the compared value is greater than the Setpoint value. The Low Setpoint
turns on when the compared value is equal to or less than the Setpoint value.
Set Setpoint xValue (Set SP) {00000 to +/-99,999}
Setpoints 1-4 can be set for any value from 00000 to +/-99,999. This value along with the previous
selection of SP HI or SP LO determines when the optically isolated open-collector output transistors are
activated and the relevant SP enunciator is illuminated.
Hysteresis Low (HL) {000 to 200}
HL is the hysteresis value for all Setpoints set to SP LO. HL determines the value the displayed reading
must exceed the Setpoint value by before deactivating their respective open-collector output(s).
Hysteresis High (hh) {000 to 200}
HH is the hysteresis value for all Setpoints set to SP HI. HH determines the value the displayed reading
must get below the Setpoint value by before deactivating their respective open-collector output(s).

Calibration Instructions
The Model 9860 provides three (3) calibration modes. In the OFF state, the CAL1 and CAL2 manual
entry modes are disabled.
1. CAL1
2. CAL2
3. TEDS
Auto calibration when connecting to a TEDS, Template #33 configured transducer, with TEDS
sensing pin. In the TEDS AUTO MODE, the unit self calibrates to the MAXIMUM FORCE and
MAXIMUM OUTPUT values found in the TEDS transducer.The 9860 updates the CAL value to the
MAXIMUM FORCE value read from the TEDS template.
Calibration is automatic if the 9860 senses a TEDS connection and is able to read the TEDS
microchip imbedded in the transducer. Simply connect the TEDS transducer to the 9860 and apply
power. The displayed reading and analog outputs are automatically calibrated.
The TEDS parameters are stored in non-volatile memory. When the TEDS transducer is
disconnected and reconnected or a different TEDS transducer, with sensing pin, is connected, the
unit automatically self calibrates, without the need for power recycling. The TEDS LED indicates
the state of the TEDS connection. See TEDS INDICATOR AND BLINK CONFIGURATIONS for detail
description. See appendix B & C for programming instructions.
TEDS Indicator LED behavior
The following TABLE describes the functionality of the red TEDS led. The led is ON when a
combination of TEDS SENSE switch or TEDS ROM is detected. The particular combination is
indicated by the led activity. If the TEDS SENSE switch and valid TEDS ROM data are detected, the
led is ON steady. If TEDS SENSE switch is detected and valid TEDS ROM is not detected, the led

Calibration Instructions
The Model 9860 provides three (3) calibration modes. In the OFF state, the CAL1 and CAL2 manual
entry modes are disabled.
1. CAL1
2. CAL2
3. TEDS
Auto calibration when connecting to a TEDS, Template #33 configured transducer, with TEDS
sensing pin. In the TEDS AUTO MODE, the unit self calibrates to the MAXIMUM FORCE and
MAXIMUM OUTPUT values found in the TEDS transducer.The 9860 updates the CAL value to the
MAXIMUM FORCE value read from the TEDS template.
Calibration is automatic if the 9860 senses a TEDS connection and is able to read the TEDS
microchip imbedded in the transducer. Simply connect the TEDS transducer to the 9860 and apply
power. The displayed reading and analog outputs are automatically calibrated.
The TEDS parameters are stored in non-volatile memory. When the TEDS transducer is
disconnected and reconnected or a different TEDS transducer, with sensing pin, is connected, the
unit automatically self calibrates, without the need for power recycling. The TEDS LED indicates
the state of the TEDS connection. See TEDS INDICATOR AND BLINK CONFIGURATIONS for detail
description. See appendix B & C for programming instructions.
TEDS Indicator LED behavior
The following TABLE describes the functionality of the red TEDS led. The led is ON when a
combination of TEDS SENSE switch or TEDS ROM is detected. The particular combination is
indicated by the led activity. If the TEDS SENSE switch and valid TEDS ROM data are detected, the
led is ON steady. If TEDS SENSE switch is detected and valid TEDS ROM is not detected, the led

blinks FAST. If TEDS SENSE switch is not detected and valid TEDS ROM is detected, the led blinks
SLOW. A blink condition indicates a problematic situation.
If both TEDS SENSE SWITCH and valid TEDS ROM are not detected, the TEDS led is OFF. The
instrument is in one of the other calibration modes: Either OFF, ON1 or ON2.
Excitation Supply
A 10Vdc @ 120mA, short circuit protected, transducer excitation supply is provided.
The connection to the transducer is shown below. The SENSE(+) and SENSE(-) leads can also be
connected at the D-Sub connector on the 9860, rather than at the transducer. Connecting it at the
TRANSDUCER provides a more accurate excitation voltage at the TRANSDUCER. If the instrument
is only to be used with 4-wire sensors, JP2 and JP3 on the connector PCB can be solder
bridged to terminate the sense leads. Alturnatively, Pins 5 & 6 (SENSE- & EXC-) and Pins 1 & 2
(SENSE+ & EXC+) can be jumpered at the connector for the same effect.
The EXC output is short circuit protected from shorts to ground. When a short to ground is detected,
the output current is reduced to prevent damage. In most cases, removing the short will cause the
output to recover. If removing the short fails to cause recovery, recycle the AC line power.
Analog Outputs
The 9860 provides auto-calibrating ±10Vdc and 4-20mA analog output signals. The maximum output of
10 volts or 20mA corresponds to the FULL SCALE value. Both the 10V output and the 4-20mA outputs
are automatically scaled by (FS). (FS) = the display value that corresponds to the full scale spans of
the outputs, either 10V or 20mA. The ANALOG output is a digitally-scaled, real time, analog filtered
and buffered output directly proportional to the input.
Examples:
1.A 9860 reads TEDS capable transducer with a maximum capacity of 10,000 lb. FS will indicate
10000. The actual load is 4000 lb. The voltage output is +(4000/10000)X10=+4 V and
+(4000/10000)x16+4=10.4 mA.

2.A 9860 is in the ON1/OFF mode. The CAL and FS values are 10000 lb and 20000 lb, respectively.
The actual load is 50000 lb. The voltage output is +(5000/20000)X10=+2.5 V and
+(5000/20000)x16+4=8.0 mA.
3.A 9860 is in the ON2 mode. The CAL and FS values are 15000 lb. The actual load is 9000 lb. The
voltage
Output is +(9000/15000)X10=+6.0 V and +(9000/15000)x16+4=13.6 mA.
The TARE function operates on the analog output the same as it does on the digital display. The
polarity of the analog output is always the same as the input signal. However, the 4-20 mA output is
unipolar and is linear only with positive input signals. Signals less than zero are clamped and will
typically generate only 2mA on the 4-20mA output.

Appendix A
Understanding the 9860 Digital Filter Settings
The 9860 digital filter is implemented as a cumulative moving average filter. It is used to filter the output
of a 16-bit successive approximation analog-to-digital converter running at a rate of 250 conversions per
second. The filter has (2) user selectable inputs that determine the digital filter settling time and noise
rejection capabilities. The user selectable inputs are Filter (01-99) and Band (000-999).
Filter (01-99) Sets the cumulative moving average filter subset size, where i=subset size.
CAi = Xi/i + CAi-1(i-1/i). Xi is the unfiltered raw analog-to-digital converter data.
The number of readings averaged is 4x the filter subset size.
Band (000-999) Sets the unfiltered, raw analog-to-digital converter data variation limits. It is used to
determine when the cumulative moving average filter is enabled and when it is
disabled. If the magnitude of the difference between 2 successive unfiltered, raw
analog-to-digital converter data is less than the Band, the filter is enabled. If it is
equal to or greater than the Band, the filter is disabled.
When the Band is exceeded, and the filter is disabled, the Instantaneous display of the 9860 is the
unfiltered, calibrated data from the analog-to-digital converter and is read in approximately 4
milliseconds. This allows the display to follow large changes in display values, peaks or valleys, virtually
instantaneously.
If the readings are within the Band and the Filter is set to 90, the digital filter is basically averaging 360
readings using a weighted moving average. This is done in 4 milliseconds. If the Band is then exceeded, it
would take approximately 360 readings x (4ms/reading) or approximately 1.44 seconds to fully implement
the Filter subset size.
NOTE 1: The digital filter uses the unfiltered, raw analog-to-digital converter data. The Instantaneous,
Peak (PK) and Valley (VAL) readings are normally filtered, calibrated analog-to-digital converter data,
and with the exception explained above, when 2 successive readings initially exceed the Band.
NOTE 2: The analog output is implemented using the signal input to the 9860. The input signal is
amplified, buffered and auto-scaled to the calibrated reading. It is a real time display, not the step
output of a digital-to-analog converter. It is filtered by a 2-pole, 1kHz, Butterworth analog active filter.

Appendix G
Factory Calibration
The instrument has been calibrated at the factory using a mV/V standard. This calibration covers the
selected input range (either 2.5 or 5 mV/V) and provides a correlation of the mV/V input to the actual
ADC range. If necessary a mV/V calibration can be performed in the field. NOTE this may invalidate a
system calibration that had been performed by Interface.
NOTES:
Always use a precision mV/V simulator for the transducer input when performing a factory calibration.
A factory calibration must be performed if the excitation voltage selection or input range was
changed.
Do not perform a factory calibration with a TEDS transducer attached.

Appendix H
Open collector output configuration
Since open collector outputs do not produce any voltage output on their own, a pull-up resistor to a
voltage source is required to provide a voltage.
You will notice that since open collector outputs sink current to the common pin, they seem to work in
reverse. The output transistor turns on when the set point LED on the front panel is lit.
Using the standard configuration shown in figure 5, the set point output will be +5 VDC when the set point
LED is off and 0 VDC when the LED is on.
The figure to the right shows a typical
installation using the instruments internal +5v
supply with a pull-up resistor installed
between pin 15 (+5VDC) and the setpoint
output. The pull-up resistor must be chosen to
limit the current through to < 10 mA (a value
between 2.5 KΩ and 5 KΩ should be fine). If
the internal +5 VDC supply is used, the
current draw of all 4 set point outputs
together must be lower than 25 mA.
Note that in this configuration the setpoint
common (pin 9) must be jumpered to the
digital ground (pin 4).
This figure shows that when using an external
power to provide power to the set point
outputs, the value of the pull-up resistor in
ohms should be between SUPPLY VOLTAGE /
.01 as the lowest value and SUPPLY VOLTAGE /
.001 as the highest. The setpoint common (pin
9) is typically tied to the external supply
common pin.
