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.
