Accessory for plotter used in Canada's national mapping program c. 1960s-early 1990s, and is an example of the last analogue plotting devices used by the Topographic Service of Canada. With the exception of the Wild A10 [few of which were used in Canada], this machine was the most sophisticated plotter available before digital technology. This machine was converted c. 1995-96 to digitize the motions (X,Y & Z) with the addition of encoders and a control pad which interfaced to a computer. The Kern encoders and control module were installed by Terra Surveys of Ottawa when they rented this machine for the MOM project, completing the large scale mapping of Riyadh, Saudi Arabia. The A8 was on loan to Terra for the duration of the project's digital compilation stage. [Ref. 1] - Function

To contain and protect contents when not in use. - Technical

Standard case holds 15 glass scales from Group IV (imperial graduation) set supplied as standard accessory with A8 plotter. Scales are inserted in a holder directly attached to the z column and projected under strong magnification onto a ground glass screen in front of the operator. [Ref.3, p.17] The rule [glass scale] must correspond to the model scale [instrument scale] in order to enable the operator to read the elevations. Wild provided a set of 4 tables, one for each of the 4 different groups of rules [glass scales] available, to facilitate the selection of the appropriate rule and [ratio] gear for a given plotting scale. [Ref. 2, p.32] Group IV set consists of scales 1:3200; 1:3600; 1:4000; 1:4800; 1:6000; 1:7200; 1:8000; 1:9600; 1:12 000; 1:14 400; 1:16 000; 1:18 000; 1:21 600; 1:24 000; 1:27 000 feet. Rules are unnecessary when using [Kern] digital elevation counter. - Area Notes
