This guide is designed to help resolve common problems associated with failed communication between an SDI-12 sensor and iChart software. Problems can arise as a result of improper physical connections, incorrect sensor addresses, physical damage to cables or connectors, and bad SDI-12 circuits on either the sensor or NexSens data logger. To troubleshoot this problem, […]
To add battery voltage, 1) Upload all your data before adding battery voltage. This procedure will erase all data in your data logger. 2) Select “Project | Setup Device Wizard” Menu 3) Click the “Next” button 3 times to get to the “Sensor” screen. 4) Click the iSIC that you want to log battery voltage. 5) […]
Notes: 1) Power (5 to 32VDC) is supplied through Black and Red wires with Red being positive. 2) For SDI-12 interface connect both Yellow and Orange wires to SDI-12 Data lines of the data logger. 3) For RS-232 interface to the PC, connect Yellow wire to Pin 2 and Orange wire to Pin 3 […]
When connecting to a data logger in iChart, the COM port over which the computer will communicate with the logger must be selected. When using a computer with a COM port, the first port is almost always COM1 and the second port, if available, is COM2. However, if a USB to RS-232 converter is being […]
In order to make certain configuration changes on a Lufft sensor, it must be connected to the computer directly using a WSConfig cable. 1. Connect the Lufft sensor to the WSConfig cable. 2. Plug the USB cable from the WSConfig cable into the computer. 3. Open Lufft’s Config Tools Software. If not installed, please download […]
iChart does not offer a built in data manipulation option. In order to alter the data within iChart one can export the data to Excel, remove the iChart data, and re-import the altered data. 1. Open iChart with the current project file (.icr). 2. Click Help | Open Users Folder from the menu bar. 3. Open the folder named […]
Some times when iChart tries to FTP a report to a site, the FTP fail due to a firewall. Enabling Passive FTP can help work around this issue. Please follow these steps to enable it: 1. With iChart open, go to Edit | Preferences… 2. Go to the Edit/FTP tab. 3. Check the Passive FTP box in the lower […]
The following equation can be used to determine the number of days that a NexSens data logger can record data before the memory becomes full: Let N = number of parameters to log, T = log interval in minutes, and D = duration in days. D = ( 4000 * T * Floor[ 512 / ( ( N + 1 ) * 4 )] ) / […]
Data marking allows a user to exclude bad data from being displayed in a report or have it show up in a different color. 1. Open the current project file. 2. Generate a new report or open an existing report. 3. Click Project | Data Marking. 4. Select the Month for the data in question from […]
In order to calibrate and configure a PONSEL sensor, CALSENS Software and an RS-485 adapter are required. If the cable has been connectorized for use with an SDL500 data logger, a NexSens UW-USB-485R cable is required. If the sensor cable is terminated in flying leads, the In-Situ Modbus Sensor Communication Device Kit can be used. […]
