The basic movement of the meter in this instru-ment may be used by switching the functionswitch to milliammeter. Leads are connected tothe pin jacks and the instrument is used accord-ingly. External shunts may be used with thebasic 0-1 ma. movement to provide an extremelywide range of current measurement. A PNP junction transistor was used in thisunit.
