3.Determine the appropriate input signal range, i.e. 400 mV, 4 Volt, 40 Volt or 400 Volt. Also ensure that the frequency of AC source is within the specified limits.
4.Ensure that if the selected range is different from the default then change the internal range by using the Setup Software and select the appropriate range.
5.Connect the signal input to screw terminal, and ensure that the screws are tight. Failure to do so may cause electrical shock should the wires become loose and come out of the screw terminal.
6.To verify that the set up is correct, you may connect a DVM to the analog output. Once connected, power the signal conditioner and apply a known voltage from an AC source to input. Measure and compare with expected values. To custom scale the analog output proceed to the next step.
7.To view/change the scaling that relates the analog output to signal input: connect the RS232 output of the signal conditioner to an available serial port of a computer. The cable and the DB9 or DB25 connectors are available as an option.
8.Turn on the computer, start Windows 3.0 or higher and run the Signal Conditioner Configuration Setup Program.
9.Start the configuration program, you need to indicate which serial port is to be used for serial communication by checking the appropriate check box on the opening menu.
Note: It is not necessary to know the serial communication protocol. i.e. baud rate, parity, 7/8 data bit and stop bit; the program will determine this information automatically. However, it is good practice to mark the protocols used on the signal conditioner label if different from default.
10.Once the program starts it will automatically detect the signal conditioner configuration and will display a window of available options. To view the signal input click on the display on/off.
11.To change analog output scaling choose analog output scaling and enter the desired values.
12.Once the custom scaling is finished, ensure that Send Configuration is clicked, otherwise the changes will not take effect.
13.The input/output scaling may be fine tuned, while both communication and analog output are active. In fact you may make a change to the analog output in the configuration program, and watch the DVM connected to analog output of the signal conditioner follow the new settings.
14.You may save or print a particular configuration by selecting the file menu. It’s always a good practice to both print and save the scaling of each signal conditioner.

15.If the program is not able to establish communication then an error message is displayed. This happens either when the wrong serial port is specified or when the cable is
disconnected.
16.The procedure to disable Continuous Mode and change the iDRN to Command Mode is as follows:
Using HyperTerminal, or any serial communication program,
type: | Ctrl + S |
