NexSens iSIC data loggers incorporate a precision real-time clock. However, the clock can drift up to two minutes per month and regional time changes require the clock to be synchronized periodically. This can be done manually or automatically. Confirm that the computer clock is correct Open iChart with a current project iChart must be opened […]
The 12V DC (direct current) batteries used on NexSens iSIC data loggers can be charged in two ways: online or offline. It will be necessary to decide which is most appropriate for the desired application. The necessary charger type can then be determined. Online Charging: If it is essential for the iSIC to always remain powered, […]
The LED only flashes when the iSIC is booting up and does not stay on all the time in order to conserve battery power. The LED will flash immediately upon connecting the battery but only for 15-20 seconds. REV: 13G29
NexSens iSIC and SDL500 data loggers can communicate using interfaces such as SDI-12, Modbus RS-485 and RS-232. This process shows how to switch from SDI-12 or Modbus to RS-485 communication in order to allow connection to a PC. 1a. Open iChart without a current project. 2a. From the main menu select Advanced | Terminal… 3a. Select […]
It may be necessary to perform a code update while in the boot loader if the normal code update is failing. 1. Open iChart. 2. Connect the data logger to the computer. 3. Select Advanced | Terminal from the menu. 4. Select Direct connect as the Connection type. Select the PC COM Port to which the data logger is […]
It may be necessary to remove the PCB (Printed Circuit Board) from the mounting plate for inspection or replacement. 1. Remove all attached wires from the back of the PCB. Note that the specific wires will vary depending on the communication available. Note: Record all wire locations before removal if replacing the board. 2. […]
