Model CS-100-1S
Digital Retrofit

Instruction Manual

The CS-100-1S offer many features and performance capabilities to suit a wide range of applications. The unit is compatible with any voltage style strain gage, process, DC voltage/current, AC voltage/current, and Temperature, Displacement, or Pressure inputs.
Optional plug in output cards offer such features as 0-10 vdc output, RS-232, RS485, Modbus, DeviceNet, and Profibus-DP. These options can be used with software available through CSI to provide live data stream, communications capabilities, operation through PLC or other control devices. Readout values and setpoint alarm values can be controlled through the bus.

Additionally, the digital has a feature that allows a remote computer to directly control the outputs of the digital. With the RS232 or RS485 card installed, the digital can be configured using a Windows based program.

The digital has four setpoint outputs, implemented on Plug-in option cards. The plug-in cards provide dual FORM-C relays (5A), quad FORM-A (3A), or either quad sinking or quad sourcing open collector logic outputs. The setpoint alarms can be configured to suit a variety of control and alarm requirements.
This unit can be adapted to any mounting configuration. Standard issue includes an enclosure suitable for mounting on existing testing machines. The package as a retrofit offers digital with enclosure, pressure transducer or load cell, power cables, and transducer cables.

Other types of transducers can be installed which will allow for accurate display of displacement, temperature, or pressure. This makes the CS-100-1S a versatile option for any soils, concrete, prestress, or manufacturing application.


The 5 digit LED display is a variable intensity unit. Function keys on the front of the display are clearly marked to eliminate operator error. Function keys on the front of the indicator are programmable to any of a variety of functions.


All scaling and configuration parameters are password protected to avoid accidental altering. Calibration is burned to non-volatile memory and does not require a battery backup system for storage. In short, this eliminates any loss of internal programming associated with internal battery failure.

Up to 16 points can be entered during calibration. This feature allows for complete linearization of any transducer. Linearization eliminates error and improves the accuracy of the device. All CS-100-1S digitals are auto ranging. This feature allows for accuracy of the display from 1% to 100% of the testing machine range.

Once your CS-100-1S is installed on your machine, power up the unit and allow for a 15 warm up prior to use.
The display will follow a boot procedure and indicate the version of software installed.
Three different function keys have been programmed to perform the following functions. These keys are clearly labeled.
DSP Key: This key has been labeled as the PEAK display key. Pressing this key will display the maximum value obtained at the end of the test.
F1 Key: This key has been labeled as the RESET key. Pressing this key will reset the Peak display back to a non-peak level. This does not turn off the PEAK display, it simply resets the value to an at rest value.
RST Key This key has been labeled as the ZERO key. Pressing this key will allow the operator to tare the display in preparation for loading a new sample


NOTE: Assuming this device is connected to a force testing machine, we will proceed with the standard procedure for performing such a test. If this device is connected to another application, the procedure may differ slightly, but will be very similar.


Power the digital as described in the earlier section and allow for proper warm-up


Insert the sample into the testing machine and ensure proper centering and alignment requirements have been met.


Power the pump and raise the platen until daylight is limited to ". Place the control valve in the METERED position. Wait 5 seconds and press the RESET and ZERO buttons on the display.


At this time you can load the sample and follow the proper rate of loading. The front display with be labeled with the units of measurement. In most cases the load will be shown as LBF X 10. Follow the display and time your rate of loading. Adjust the flow control valve to achieve a loading rate which is appropriate to the standard for the sample tested.


As you reach failure the loading rate will decrease until the sample has reach failure. Once failure is achieved, position the control valves to RETRACT.


Shut off the pump.


Press the PEAK button and the Maximum value achieved during the test will be displayed


Remove the sample, and record your test values.


Proceed to Step 2 to start your next test.


ASTM recommends annual calibration. Devices should be calibrated upon installation, or when any major changes or repairs are made to the loading system which may affect the integrity of the testing machine accuracy. Please contact CSI for calibration or service. Our dedicated staff will provide you with quality calibration and service at affordable prices.

During period of warranty, to maintain warranty status, CSI (or a CSI approved agent) must perform all calibration and service to your CS-100-1S retrofit.


This device works well will any concrete, soils, mechanical, or stressing application. It is a great replacement for analog gauge machines, or devices which do not allow for data transfer to your PC. Should you ever loose calibration on the device, the unit allows for easy entry of calibration parameters to eliminate down time.

Contact CSI should you experience any difficulty. We would be glad to offer assistance in any reconfiguration or service which may be necessary to keep your retrofit in top operating order.
