Operator's Guide

The primary gain block of the 5T is normally set at × 1 (unity). If

higher sensitivity is required, the gain of the instrument can be altered

by inserting gain-setting resistors onto the power supply board of the

unit:

If G is the gain change you require, then the value of the resistors to

insert is given by the formula

R = 10000 / (G – 1)

Care must be taken when soldering these resistors to the circuit board,

as overheating the terminal could easily damage surrounding circuit

elements.
