The NexSens iSIC is powered from an internal battery. The addition of a float charger or solar panel can provide constant re-charging of the battery for prolonged use scenarios. Before data can be retrieved from sensors, power must be supplied to the iSIC. To do so, open the iSIC enclosure and unscrew the battery mounting […]
Electronic circuits are susceptible to voltage surges. The iSIC has on-board transient voltage suppression devices. Connect the ground lug to a proper electrical ground (i.e. earth ground or a properly grounded pipe/metal fixture). For outdoor applications, use the copper wire supplied with the A38 ground kit to connect the ground lug to the rod’s ground […]
NexSens recommends the A55 mount kit be used for all outdoor applications when mounting to metal poles, wooden posts, or walls. The A55 kit includes a ¼” aluminum plate, u-bolts, and lag screws. Use the supplied u-bolts for mounting to metal poles less than 2 3/8” diameter. Attach the plate to the enclosure using the […]
Due to the nature of many environmental projects, immediate notification of failures is a necessity. The iChart System Monitor allows a project manager to receive critical messages such as failure to retrieve data or upload data online. Click Project | Project Monitor. The System Monitor will appear. The Status tab of the System […]
iSIC alarms are used to change the functionality of the data logger based on parameter inputs, such as changing sample and log intervals based on a particular logged reading. Open iChart with the current project. Click Setup. In the Setup Device window, click the iSIC Alarm tab. Place a check in the […]
Parameter alarms configured on the iSIC data logger allow users to setup and configure controls to do things such as flash warning lights, trigger ISCO samplers, etc. The iSIC allows two kinds of control, 3.3V digital I/O and 12V 100mA switches. These can be accessed via the Setup Device Wizard in iChart. This may be […]
The following information is only for customers who have V6 circuit boards. MS8 Connector Wiring On the outside of the iSIC enclosure is an MS8 connector which is used for sensor wiring. This connector allows for quick connection for instruments such as YSI Sondes, which has a mating MS8 connector at the end of its […]
Digital I/O uses a voltage signal to represent either a one or a zero. A “0” typically ranges from 0 volts to 0.8 volts while a “1” will range from 2.4 volts to 5 volts. These ranges are defined in the TTL (Transistor-Transistor Logic) specification. Environmental data loggers can use digital I/O ports for […]
When testing a pulse counter functionality, it is sometimes required to view and reset the current number of “tips” on the pulse counter. For example, with tipping bucket rain gauges, the best method to ensure accuracy is to pour x amount of water through the bucket to make sure it records x number of tips […]
A tipping bucket rain gauge can be connected to the iSIC through the digital terminal strip. Follow the connection diagram below to properly connect a rain gauge. One rain gauge may be connected to the iSIC at a time. REV: 13G02
