Warning:
Verify that the power supply connections are correct before powering on.
Note:
Make sure that the power cord does not pose a potential obstacle or tripping hazard. Only use approved accessories and peripherals.
Load Cell Connections:
The 9825 indicator uses a 6-wire load cell signal connection. This indicator provides a 4.5 volt DC excitation voltage to the load cell(s). The voltage difference between +SIG and -SIG is about 0 ~ 9mV when connected to a load cell with a 2mV/V output, and about 0 ~ 13.5mV when connected to a load cell with a 3mV/V output. The 9825 indicator can drive up to six (6) 350-ohm load cells (or the equivalent resistance of all load cells connected in parallel is higher than 87).
If the application requires the 9825 to be connected to multiple load cells, please use a junction box.
Note:
This product does not contain a junction box. If a junction box is necessary for your application, we recommend Interface Model JB104SS as an approved accessory.
The load cell cable requires a shield which must be properly grounded to ensure maximum stability. High quality cable is recommended. Be sure to route the load cell cable away from high voltage / power cables. The maximum length allowed for the load cell or junction box cable is shown in the following table:

Calibration Procedures:
Calibration Overview:
The 9825 Indicator can be calibrated by using either a Live calibration method or a Key-In calibration method. It is important to set the Nominal Capacity Value before beginning calibration.
Live Calibration:
The Live calibration method produces the best possible system accuracy. This method requires one of the following:
- The load cell being paired with the 9825 Indicator will be connected to the instrument while a series of nominal force loads are applied to calibrate the instrument.
- A load simulator will be connected to the 9825 Indicator while a series of simulated mV/V loads are applied to calibrate the instrument.
Live calibration is accomplished by setting the Positive Span, Negative Span and Zero. To execute a Live calibration, follow the steps below:
1. Press and hold the Menu button to enter the setup menu. A beep will sound as the setup menu is activated.
2. Using the (Menu) button, scroll until Calibration is displayed on the screen. Press the (Pk/Val) button to enter the calibration sub-menus.
3. Using the (Menu) button, scroll until Set Pos (or Neg) Span is displayed on the screen. Press the (Pk/Val) button to initiate the calibration process.
4. The term Fixture will show on the screen. At this point the load cell should be set into its fixturing, but with no additional calibration loads applied. If a simulator is being used for the Live calibration, connect the simulator, but set its value to 0mV/V. Press the Menu (Enter) button to save this point.
5. After the Fixture value has been set, the term C1 (calibration point #1) will appear on the screen. The user should set the numerical field so that it displays the nominal force load that is about to be applied. Once this value has been input and the applied force load has stablized, pressing the Menu (Enter) button will capture this point.
6. The C2 term will then appear. If the user would like to add another calibration point (up to six are possible) they can repeat the actions in Step 5. If the user would like to end the calibration, they should leave the numerical field as 0 and press the Menu (Enter) button.
Note: if the calibration was unsuccessful, an error message will appear:
- "Err2" : There is not enough signal from the load cell. This is most commonly caused by incorrect wiring or a damaged load cell.
Repeat this process in the opposing polarity, than proceed to Zero calibration.

9825 Installation & User Manual 15-386
Zero Calibration:
1. Press and hold the Menu button to enter the setup menu. A beep will sound as the setup menu is activated.
2. Using the (Menu) button, scroll until Calibration is displayed on the screen. Press the (Pk/Val) button to enter the calibration sub-menus.
3. Using the (Menu) button, scroll until Set Zero Point is displayed on the screen.
4. At this point, the Zero Calibration is ready to begin. Be sure the load cell is connected and in an unloaded state. If using a simulator, be sure that the simulator is set to 0mV/V. Press the (Pk/Val) button to initiate the Zero Calibration. Dashed lines will be displayed at the bottom right of the screen to indicate that the 9825 is capturing the zero point.
Key-In Calibration:
The Key-In calibration method is typically only used in emergency cases when the indicator cannot receive a Live calibration. The Key-In method uses a single point to establish the span of the load cell. It ignores load cell nonlinearity and any asymmetry between the opposing loading modes.
To execute a Key-In calibration, follow the steps below:
1. Press and hold the Menu button to enter the setup menu. A beep will sound as the setup menu is activated.
2. Using the (Menu) button, scroll until Calibration is displayed on the screen. Press the (Pk/Val) button to enter the calibration sub-menus.
3. The Live or Key-In sub-menu is the first Calibration sub-menu and should be displayed on the screen. Press the (Reset) button to change the flashing value from Live to Key-In. Press the Menu (Enter) button to save this setting.
4. Press the (Menu) button to change the sub-menu to Rated Output. Press the (Pk/Val) button to enter the Rated Output sub-menu.
5. Enter the sensitivity of the load cell into the numerical field. This is typically the mV/V output of the load cell at its rated capacity. Press the Menu (Enter) button to save this value.
6. Press the (Menu) button to change the sub-menu to Sensor Capacity. Press the (Pk/Val) button to enter the Sensor Capacity sub-menu.
7. Enter the rated capacity of the load cell into the numerical field. Press the Menu (Enter) button to save this value.
8. Press the (Menu) button to change the sub-menu to Set Zero Point. User should preform a Zero Calibration as detailed above.

Industrial Interfaces
USB Interface Communication:
The 9825 indicator can connect to a PC via USB cable. First a USB driver must be installed on the PC to access the 9825. Measurement data can be accessed by using a terminal emulation application such as HyperTerminal. The USB Port output has Two fixed strings: ASCII and Condec.
Analog Output Interface:
Analog Output Calibration:
The mode of the Analog Output can be selected from its Output Type sub-menu. There are four modes of analog output: 4-20mA, 0-24mA, 0-5V and 0-10V. Please refer to the wiring section for the proper jumper setting of the optional analog output board. To calibrate the Analog Output, follow the steps below:
Scale Output:
1. While within the Analog Output menu, scroll to Scale Output and press the (Pk/Val) button to initiate the Scale Output sequence.
2. Scale Output is set by inputting a Low and High force value. To set a given value, use the numerical field on the screen to input the desired force. The first character can be used to switch the sign convention from + to - and back. Press the (Pk/Val) button to save the setting.
Fine Tune:
Before performing this part of the device setup, the Analog Output of the 9825 should be connected to whatever instrument will be accepting and measuring the analog signal.
1. In the Analog Output setup menu, scroll to Fine Tune and press the (Pk/Val) button to initiate the Fine Tune sequence.
2. The screen will display "0%", which indicates the lowest point of the analog scale. For voltage outputs, this is 0VDC. For current outputs this is either 0mA (0-24mA) or 4mA (4-20mA).
3. By adjusting the numerical value on the screen, the Analog output will be Fine Tuned. The digit furthest to the left creates the greatest change in output, while the digit furthest to the right creates the smallest change in output. Adjust this number until the measured value on the connected meter or PLC shows the minimum point on the analog scale. Press Menu (Enter) to save this value and proceed.
4. Repeat this process for the 50% point. For a 0-5V setting the output will be 2.5V. For a 4-20mA setting the output will be 12mA and so on.
5. Repeat this process for the 100% point.
Notes: - The analog output mode setup to 4mA-20mA: If the load 0kg, the voltage output is 0. If the load is the full range of the scale, than the voltage output is 24mA.
- The analog output mode setup to 0-10V: If the load 0kg, the voltage output is 0. If the load is the full range of the scale, than the voltage output is 10.8V.
