X.3362 - LIGHTING INSTALLATION AT W+W.

Mr. Royce requires for the above installation a small Weston switchboard ammeter with central zero reading 30/0/30 amperes. Will you kindly write to the Weston Instrument Company and ask them if they can supply one of their model 269 or 271 instruments arranged for this range. You might suggest that if they cannot supply this with a 30/0/30 range, a 25/0/25 would do for the purpose.

This ammeter should be ordered under order number 49820 and should be charged to Mr. Royce's private account.

EFC.
