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 […]
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-232 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 […]
Solar panel kits may be connected to iSIC data loggers to recharge the 12V A01 iSIC battery. Solar charging kits are equipped with a charge regulator to prevent overcharging of the A01 battery and damage to the data logger or connected devices. Use the following process to identify and troubleshoot suspected issues with a solar panel kit. 1. […]
It may be necessary to reset an iSIC or SDL by manually cycling power. This will allow the system to reboot and can solve various problems. iSIC 1. Open the lid of the iSIC enclosure. 2.
