| ROY.{Sir Henry Royce} from Hs{Lord Ernest Hives - Chair}/Wst. x2434. Hs{Lord Ernest Hives - Chair}/Wst.18/KT.31.3.33. WESTON LABORATORY INSTRUMENT. We have in the electrical laboratory a Weston standard instrument Model 1, No.32901 arranged as a self contained voltmeter with ranges 1.5, 15 and 150, and with an external shunt box having .15, 1.5, and 15 ampere shunts. Will you please ascertain from the Weston Electrical Co. whether they could accomodate a 30 ampere shunt in the existing box and what would be the estimated cost. If they cannot accomodate the extra shunt in the box would they please quote us for a separate 30 ampere shunt for the above instrument. Hs{Lord Ernest Hives - Chair}/Wst. | ||
