This general purpose Multi-meter was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England. This particular meter was manufactured in the Netherlands. This type of "old" analogue meter was replaced by digital meters whose electronic components are a fraction of the size of the older analogue ones.This analog General Purpose multi-meter is quite a large (for handheld mobile) apparatus which permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This General Purpose Multimeter is an analogue meter i.e. it has a needle arm that moves across a scale of divisions. This is a large(hand held) device due to the mechanical movement system within and the large size of its electronic components of its circuitry.There are two black bake-lite push buttons operating the wire inserts Positive/negative leads at the top. The meter (protected with a glass window) has clearly marked graduations (top - volts, bottom amperes). Below this are two bake-lite dials (left "potentiometer the right one measuring range selector). Below this is a "dial" switch to input the desired resistance measuring range "V" Front "H&B ELIMA" and to the right Elavi 15n. 0n the front side is a label "STATE ELECTRICITY COMMISSION OF VICTORIA TRANSMISSION DEPT E.C.No." On the bottom of the base is a stenciled layout of the battery "layout" including the fuse . The information notice is presented in five languages starting with German, English,French, Italian, Spanish and Dutchsec vic kiewa hydro scheme, alternate energy supplies, alpine population growth

This leather case holder for a general purpose Multi-meter( KVHS 0307 (A)) was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England. This particular carry case was manufactured in the Netherlands. This carry case for an analog General Purpose multi-meter which is quite a large (for a handheld mobile) apparatus.The bag however permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical generators.

Multimeter, therefore it is made from thick leather. It has a carrying strap from a thick "D" chromed link. This link is fastened to the main cover by a looped leather strip with a black coloured rivet. All the fasteners are either chrome or black coloured rivets. The front, which when opened back exposes fully the inside of the case. It is clip fastened to the lower section of the front piece which also can be pushed back allowing the meter to be removed from the frontal position. There is a strip retaining strap slightly higher from the mid point. This is fasted by a black press stud. There are two "L" shaped tin protrusions allowing the meter to slide only down the case until it rests on these shelves. This provides for an empty space for minimal storage,.On the front bottom and below the clasp is a tag "STATE ELECTRICITY COMMISSION OF VICTORIA TRANSMISSION DEPT."sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth
