PCE Instruments - Model PCE-LOC 20 - Current/Voltage Data Logger
For Simulation and Measurement of Current and Voltage / Li-Ion battery / Continuity tester / Ramp function / Data logger. The current/voltage data logger PCE-LOC 20 can be used to directly simulate process currents in current loop, mV and mA. This allows the current/voltage data logger to be used to set process displays, data loggers, paperless recorders, etc. Thanks to the galvanically isolated connections, this current/voltage data logger can simultaneously serve as a source and as a measuring device. Here, it does not matter whether currents are measured and voltages are simulated, since the functions work completely independently of each other.

The current/voltage data logger PCE-LOC 20 has a high accuracy of 0.02% of the measured value in all operating modes. The current/voltage data logger is powered by a rechargeable battery that can be charged via a USB power adapter. The memory can also be read out by the current/voltage data logger via this interface. For ease of operation, the LCD contributes from the current/voltage data logger.
In addition to the direct specification of the simulated parameters, the current/voltage data logger has a ramp mode that allows the parameters to be changed incrementally and automatically over a defined period of time. The current/voltage data logger PCE-LOC 20 can also specify the scaled process value. This means, for example, that a temperature in °C / °F is specified directly and the current/voltage data logger simulates the analog process value in mA.
