Supply voltage effect: ±0.005 % of span/V Insulation resistance: ≥ 100 MΩ with 500 V DC Dielectric strength: 1500 V AC @1 minute (input to output to outdoor enclosure) Safety integrity level according to IEC 61508: Suitable for use in a safety instrumented system up to SIL2 (together with sensor) if appropriate safety instructions are observed. Consult M-System.
HOW TO CALCULATE ACCURACY AGAINST SCALE Example: 4 – 20 mA input, Scale 0 – 100 Accuracy = 0.01 mA ÷ (20 – 4)mA × 100 = 0.063 % Display Error = (100 – 0) × 0.063 % = ±0.063 digits
