PRINCIPLES OF OPERATION

Primary Alternating Current (Ac) Power Circuit

The ME-526A/USM can be operated from a 115 or 230-volt, 50 to 400-Hz source. A slide switch, indicating 115 or

230, connects the primary of the ME-526A/USM power transformer in parallel for 115-volt operation or series for 23

volt operation. A 0.20/A (ampere) fuse (115-volt operation) or a 0.10 A fuse must be installed.

RECORDER Output

A dc voltage is present at the RECORDER terminals that is proportional to the rf millivoltmeter digital display. When

the digital display is full scale, the voltage at the RECORDER terminals will be 10 volts dc with the polarity marked on

the front panel.

Connections for Remote Operation and External Programming.

External connections can be made to the ME-526A/USM for remote operation and external programming. Additional

equipment, not supplied with the ME-526A/USM, is required for this function.
