But they're actually brilliant for generating +/- 0-10V, 0-22mA and 4-20mA sources. The menu is a bit confusing when you first look at it, but it doesn't take long to get the hang of it and they really are very useful pieces of equipment. 👍 ## Features - Various output ranges can be set (factory default 0-10V/0-20mA). - Current output 2, 3, 4-wire passive and active are fully compatible. - Voltage -10V to +10V (factory setting 0-10V), can be set by yourself: 0-10V, 2-10V, 0-5V, 1-5V, 0-3.3V, 0-2.5V, 0-1V, + 10V, +5V, -10V-0V. - Output with short circuit protection, power supply with reverse polarity protection; - Power supply mode: external DC15-30V/USB-5V ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6FBJ3QH | | Best Sellers Rank | 15,632 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 6 in Function Generators | | Brand | Fasizi | | Colour | Black | | Country Of Origin | China | | Customer Reviews | 4.1 out of 5 stars 72 Reviews | | Manufacturer | Fasizi | | Measurement Type | Multi-function Electrical Tester | | Min.
