4 galvanically isolated voltage inputs allows measurement of any voltage you want. 0-5V input range and 16-bits at 15 Samples Per Second is ideal for low voltage high precision acquisition. Includes a Programmable Gain Amplifier (PGA) for measuring even lower voltage signals.
Ideal for measuring a series stack of lithium-ion cells in a battery, or for removing the possibility of ground loops when measuring different sources. Up to 32 devices can be daisy-chained with RS485 communication layer for up to 128 analog inputs.
SCPI interface is available on the USB port. This device can interface with Python through PyVisa. I have created a python library for this device as well as a GUI for calibrating it automatically using another programmable multimeter and power supply.
GUI and SCPI example are available here: https://github.com/mbA2D/Test_Equipment_Control
