Meter Output
Proportional 0–1 mAdc, filtered, for meter or recorder loads up
to 750 Ω.
Supply Output Regulated +14 Vdc ±5%; 40 mAdc (maximum load)

and Noise
0.1% of full-scale maximum over 10% to 100% of full-scale.
Response Time 150 milliseconds, 10% to 90% rise (standard). Full-scale
frequency ranges below 80 Hz are proportionally slower.
Linearity 0.1% of full-scale (0.05%, typical), all outputs.
Stability Less than 0.05% of full-scale change with a 10% change in
supply voltage. Temp. coeff. ±0.01% per °F (±0.018% per °C)
