This manual provides a detailed overview of the GP2 Data Logger Controller and how to use it
The GP2 is a research-grade logger controller capable of complex calculated measurements and advanced feedback control. It features 12 differential analogue input channels, four event/digital counter channels, and a serial input channel for SDI-12 sensors. The device supports multiple recording rates and types, including average, minimum, maximum, and conditional logic, allowing it to store approximately 2.5 million readings.
| Analogue Input Channels | 12 differential |
|---|---|
| Event/Digital Counter Channels | four |
| Serial Input Capacity | up to 62 SDI-12 sensors |
| Storage Capacity | about 2.5 million readings |
| Relay Control | Two output relays (extendable to 6) |
| Relay Switching Capacity | 1A at 24VAC or 32V DC |
| Input Signal Range | -1.4 to +2.7V |
Two flashes per ten seconds means the GP2 is logging, while four flashes in a group indicate an error.
Hold the Reset button for more than 5 seconds until a second set of four LED flashes occur.
The logger can hold about 2.5 million readings.
