DECIMAL PLACE
The meter is not auto-ranging and so the range of interest and the accuracy is set by the
operator depending upon the span used and the accuracy of the signal or transducer. As a
rule of thumb choosing additional decimal places makes it easier to set the alarm levels
accurately. Gas monitoring generally should not use more than one decimal place for
practicality.
SB2(1) 0.00
SB2(2) 00.0
Note: If both switches are in the off position then no decimal places are shown 000
RELAY INVERSION
For some monitoring applications such as oxygen monitoring one is concerned that the
concentration not fall below certain values. In these instances switches on switch block 3 invert
the alarm trips so that the relays/alarms actuate as the signal falls below the setpoint.
SB3 (1) Low alarm invert
SB3 (2) High alarm invert
