WEIGHT: 0.6 kg (1 lb, 5 oz)

0.00 to 24.00 mA; -25.0 to 125.0 % of 4 to 20 mA; % DP Flow

ACCURACY: ±(0.05% of 24 mA Span + 0.01 mA) = 0.02mA

1Typical 90 day accuracy can be estimated by dividing the 1 year
% of full scale accuracy by 2. Additions to the specification, such
as + 1 LSD, remain constant
