This device facilitates the measurement and calibration of the mainfraimes HM8001 and HM8001-2.
In this way, you can measure and calibrate all output voltages of the HM8001 and HM8001-2 in no-load and under load in just a few simple steps.
In addition, the rotary switches provide various components at the outputs that you need for calibrating other Hameg devices.
For each plug on the front panel an each position of the rotary switch , the number of the internal connection (see circuit diagram) of the mainframe is shown.
