APPENDIX 8 SPECIFICATION
1. Functional Characteristics
Display: Digital LED display reading 0-100% oxygen with 0.01%
resolution and over range capability.
Analogue output: 0/4 - 20 mA or 20 - 4/0mA isolated, selected by the keyboard.
Maximum impedance 600 ohms.
Option of the output to be intrinsically safe "ib" when it is
connected to ground (ie non-isolated).
Spans 1, 2, 2.5, 4, 5, 10, 20, 25, 40, 50 and 100%.
The 1% span is not available with the 1100H.
2, 4, 20 and 40% spans and reverse output are not available
with software 0110066X.
Zero suppression: The zero may be suppressed in 0.01% steps to a maximum of
99.99% suppression.
Power supply: 100, 110, 117, 220, 240V ac, +/! 10% 48-62Hz 200VA.
