1.3 What is the SC Series?
The SC Series of Signal Conditioners/Indicators are versatile, multi-channel devices
designed to operate with many different types of sensors. Several different chassis
types, Input channels, and Output channels are available to allow the configuration of
an SC instrument to meet a variety of measurement and control needs. The operation
of an SC instrument is based on digital technology to provide improved accuracy,
superior ease of setup, and a wealth of features.
1.3.1 Features The main features of the models SC1000, SC2000, SC2001 and SC3004 are:
• Four alarm limits (optional sixteen), with versatile setup (not available on Model
SC1000)
• Automatic setup, calibration, and scaling of strain-gage sensors through the use
of Signature CalibrationTM
• Field selectable, digital, low-pass filtering (“damping”) on each Input channel
• Up to ±50,000 part resolution
• Field selectable five-, six - or seven-digit (9,999,999 maximum) display
• RS-232 communications standard (RS-485 optional)
• Local or remote setup using the RS-232 or RS-485 port
• Push-button on/off tare feature
1.3.2 Chassis Models Several models (i.e. chassis types) are available:
•SC1000: 1 to 4 physical channels, 3/8 DIN case, no limits or peak detector
•SC2000: 1 to 4 physical channels, 3/8 DIN case
•SC2001: 1 to 4 physical channels, portable case
•SC3004: 1 to 14 physical channels, 19” rack mount case, 1 to 3 quad-line displays
1.3.3 Channel Types Channels can be one of three types: Input, Output, or Virtual
Input Channels Input channels are hardware circuit boards with a unique channel number. Currently,
they are available for the following types of sensors:
• Strain-gage sensors, such as unamplified pressure transducers and load cells
• Sensors with voltage outputs, such as transducers with the Option 2a, 2b, 2c, 2d,
2g, 2j, 2k, 2p, 2t or 2y internal amplifier
• Sensors with current outputs, such as transducers with the Option 2j, 2k or 2n
internal amplifier
• AC-AC LVDTs (Linear Variable Displacement Transducers)
• DC-DC LVDTs
Output Channels Output channels are hardware circuit boards with a unique channel number. They
include:
• Relay Output channels, which can add additional limits to the standard four (N/A
on Model SC1000).
• DAC Output channels, which provide additional voltage or current outputs.
Virtual Channels Virtual channels are software based devices that occupy a channel number, but not a
physical slot, in an instrument.
• Split Display Virtual channels allow the displaying of any two channel’s track, peak
or valley values at the same time.

SC Series Instruction Manual page 13
Introduction1
• Mathematics Virtual channels run small programs written in an interpretive
language called SensoCode. This provides great flexibility which allows the
SC Series to do many jobs which otherwise requires a personal computer or
PLC.

page 14 008-0608-00
1.4 What is Signature Calibration ?
1.4.1 Overview A small integrated circuit is located either inside the transducer, in an in-line package
between the instrument and the transducer, or in the connector of a cable. All data
necessary to set up the transducer with the instrument are stored (even linearity data),
and setup is automatic when a new transducer is connected to the instrument.
The Strain-Gage Input channel of the SC Series is designed to operate with Signature
Calibration. It will automatically set itself up with transducers which contain the mem-
ory device, but can also be set up using a front-panel interactive procedure. The Sig-
nature Calibration module can also be programmed from the instrument’s front panel.
Signature Calibration is only available with unamplified strain-gage transducers.
1.4.2 Benefits The benefits are:
• The transducer’s Calibration Record is always located where it is needed most...
with the transducer.
• The instrument is always set up correctly with the transducer.
• Interchanging of transducers and instruments is a quick process.
• A User Calibration Data area that can be altered by customers to fit their require-
ments.
• A Factory Calibration Sheet Data area, unalterable by the customer, can be cop-
ied back into the User Calibration Data.
1.4.3 Information
Stored
The following information is stored inside transducers equipped with Signature Cali-
bration:
• Full-scale mV/V: The full-scale millivolt-per-volt (mV/V) rating of the transducer
when its full load is applied; also called “calibration factor”.
• Shunt-Cal mV/V: The millivolt-per-volt output of the transducer when the shunt
calibration resistor is placed across its (-)SIGNAL and (-)EXCITATION leads.
• Shunt Resistance: The resistance value, in Ohms, that was used to obtain the
shunt-cal mV/V value above.
• Full-Scale Value: The full scale value of the transducer, in engineering units.
• Engineering Units: The engineering units that the transducer is calibrated in (i.e.
pounds, grams, pascals, inches of water, etc.).
• Serial Number: The serial number of the transducer.
• Excitation Voltage: The magnitude and type of signal used to excite the trans-
ducer.
• Linearization Points (optional): These can be used by an instrument using Shunt
Calibration or Millivolt-per-Volt Calibration to correct any non-linearity in the trans-
ducer and thus improve the accuracy of the system. An additional “multiple-point
calibration” can be purchased with the transducer that allows linearity correction
information to be placed into its Signature Calibration module.

Getting Started Quickly2
Chapter 2
Getting Started Quickly
2.1 Locate Required Parts and Information
The following items are required to set up an SC Series instrument with your
transducer:
• SC Series instrument
• Transducers that are to be connected to the instrument
• For each transducer to be connected to the instrument, a connecting cable.
This cable will have a 12-pin, green, plastic connector on one end and the
transducer’s mating connector on the other end. Usually, this cable is ordered
along with the instrument and transducer.
If the connecting cable was not ordered with the instrument, you may need to
make this cable.
• The transducer’s Calibration Record or Certificate of Calibration.
• The Customer Information Sheet that shipped with your instrument. This
sheet describes which cards are installed in each channel.
• Power cord for the instrument.
2.2 Connect the Transducer to the Correct Channel of the Instrument
For each transducer, attach its connecting cable to the transducer, and then to the
correct 12-pin channel-connector on the instrument.
The Customer Information Sheet indicates which serial numbered transducer is to
be connected to each channel of the instrument.
If the instrument and transducer(s) were not purchased with a connecting cable,
you may need to make this cable. For the transducer’s pin connections, see that
transducer’s calibration record. For the pin connections for that channel of the
instrument, see the appropriate chapter in this manual. For example, if you wish
to wire to a Strain-Gage Input Channel see the chapter “Strain-Gage Input Chan-
nel” on page 59.

page 16 008-0608-00
2.3 Turn on the Instrument
Connect the power cord between the instrument power source and the instrument,
and turn the On/Off switch on the back of the instrument to the On position.
The instrument enters its INITIALIZE mode that lasts a few seconds per channel. As
each channel in the instrument is initialized, the transducer's serial number may be
seen on the display if the transducer has a Signature Calibration Module in it.
When the instrument enters its normal operating mode (RUN mode), you will see the
following format on the front panel display:
1 • 00000. PSIG "
where:
•Channel number: “1” is the channel number.
•Value type: The next character indicates the nature of the following value.
A blank character indicates the tracking value. The instrument is “tracking” the sig-
nal, continuously updating the display in response to the signal from the trans-
ducer.
A “•" character indicates the peak value (highest value seen since the [CLEAR]
button was last pressed).
A “–" character indicates the valley value (lowest value seen since the [CLEAR]
button was last pressed).
•Data value: “00000.” displays the value from the transducer in engineering units.
•Units label: “PSIG” indicates the engineering units being used (up to 4 charac-
ters).
•Tare indicator: A “"“ symbol indicates tare is off; a “Ë“ symbol indicates tare is on.
NOTICE
If the channel’s display flashes “ APPLY 00000. ” (or some other load value), the
instrument has detected a transducer other than the one which was last cali-
brated with that channel. The instrument is prompting you to apply the
requested load to the transducer so that a “mV/V Calibration” or a “Shunt Cali-
bration” can take place.
After making certain that the correct transducer is connected this channel,
press the [ENTER] button after you have applied the requested load to perform
the calibration.
NOTICE
If the instrument displays error code 57 or 68, it has detected a transducer
other than the one which was last calibrated with that channel. Furthermore,
the channel cannot perform an automatic calibration because its calibration
type has been set to “Known Load Calibration”.
Either re-connect the correct transducer to the channel, or see “
CALIBRATION
TYPE
Menu Item” on page 67 to select another calibration type.

Getting Started Quickly2
2.4 Use the SETUP Menus to Enter Transducer Information
You can skip this step if:
• You are using a transducer equipped with Signature Calibration, or
• The transducer and instrument were purchased together and set up by Sen-
sotec.
Otherwise, you must enter information about your transducer into the SETUP
menu of the channel to which it is connected. See the appropriate chapter of this
manual for that card type.
2.5 Calibrate the Transducers to Their Channels
You can skip this step if:
• You are using a transducer equipped with Signature Calibration, or
• The transducer and instrument were purchased together and set up by Sen-
sotec.
Otherwise, you must choose a calibration method (e.g. Shunt Calibration, mV/V
Calibration, or Known Load Calibration) appropriate for your application and use
the SETUP menu for that channel to calibrate the channel to the transducer. See
the appropriate chapter of this manual for that card type.
2.6 The SC Series Instrument is Ready for Use
See “RUN Mode” on page 20 for information on how to operate the instrument
while it is in the RUN mode.
Apply some test stimulus on the transducer to observe changes in the display.

Operating Modes3
Chapter 3
Operating Modes
3.1 Operating Modes
The SC Series instruments have four modes of operation:
• INITIALIZE, to test the instrument upon power up
• RUN, normal operation
• ERROR, which indicates that an abnormal situation has occurred that
stopped the operation of the instrument
• SETUP, a menu which allows setup and calibration of the chassis and its
channels
Each of these will be described in this chapter.
3.2 INITIALIZE Mode
When the instrument is powered up or otherwise reset, it enters the INITIALIZE
mode. As the instrument enters this mode, all segments of the display and all
front panel indicator lights (if available) illuminate momentarily. Next, each channel
in the instrument is checked for proper operation.
If a problem is detected, the instrument may enter the ERROR mode.
Depending on the type of channel, other actions may occur. For example, a
Strain-Gage channel will calibrate its analog-to-digital converter and attempt to
read the transducer’s Signature Calibration information. If the transducer is
equipped with Signature Calibration, the transducer’s serial number is displayed
momentarily.

page 20 008-0608-00
3.3 RUN Mode
After the INITIALIZE mode finishes, the instrument enters the RUN mode, its normal
mode of operation.
3.3.1 Display
Model SC3004 and upper
line of SC1000, SC2000,
SC2001
The display will show a channel number on the far left, followed by the channel’s oper-
ation messages.
For example, a Strain Gage amplifier channel will use the format below:
1 • 00000. PSIG "
where:
•Channel number: “1” is the channel number.
•Value type: The next character indicates the nature of the following value.
A blank character indicates the display is being continuously updated by “tracking”
the input signal to the channel.
A “•" character indicates the peak value (highest value seen since the [CLEAR]
button was last pressed).
A “–" character indicates the valley value (lowest value seen since the [CLEAR]
button was last pressed).
•Data value: “00000.” displays the value from the transducer in engineering units.
•Units label: “PSIG” indicates the engineering units being used (up to 4 charac-
ters).
•Tare indicator: A “"“ symbol indicates tare is off; a “Ë“ symbol indicates tare is on.
Lower Line of SC1000,
SC2000, SC2001
The contents of the display’s lower line is selected with the “ DISPLAY MENU -> LOWER MODE ”
menu item as either displaying a channel or indicating the status of Limits. See “Indi-
cator Lights” on page 21.
3.3.2 [VALUE] button
After the channel number, the next characters indicate which data value for the dis-
played channel is shown. There are three (possibly four) data values available from
each channel:
• (blank), tracking data value
•“
•", peak data value, (highest value since the peak/valley detector was cleared)
•“
–", valley data value, (lowest value since the peak/valley detector was cleared)
•“
Û ", percentage of the Analog-to-Digital converter’s full-scale digitizing capability.
This data value is only available when the channel’s “
DIAGNOSTICS -> DISPLAY ADC ”
menu item is set to “ON”.
Pressing and releasing the [VALUE] button cycles though the available sources for
data values for the displayed channel.
3.3.3 [CLEAR] Button Pressing and releasing the [CLEAR] button will reset the peak and valley values of the
channel being monitored by the display to the track value. Additionally, any limits in
the instrument that are “latched” will be reset.
NOTICE
The [VALUE] button is not used by SC1000 instruments in the RUN mode.
NOTICE
The [CLEAR] button is not used by SC1000 instruments in RUN mode.
