summary:

XSD multi-channel display instrumentIncrease the number of measurement and display channels to reduce equipment costs，

There are three types: 2-channel, 3-channel, and 4-channel. Basic functions are consistent with XST series

Same (without 8-segment line correction)，Independent setting of input signals and ranges for each channel；

Each channel calibration and independent setting of digital filtering.Instrument power supply 220V AC, 24V D

Or 12V DC，Appearance and panel form: 160×Various panel forms or LCD displays of 80.
