(2) Span (range)
■ SpHii can be set and displayed as follows for flow vdociiy and flow rales:
• blow velocity: OI .OOG m/s (three digits after the decimal point)
• Flow rales: 2.83E+3 mVU (three digits and exponential)
■ Valid range of span is U.l m/s to 10 rill's in terms of flow velocity,
If you try to set ihc span outside of this range, one of the following messages appears:
* K OVER SPEC- (it the set value exceeds 10 nv's)
* L OVER SPEC, (if the set value is less than 0,1 ni^s)
fry again to set the span within the specified range.
■ When multiple ranges arc used, tbc following must be observed;
* Range 1 > Range 2 > Range 3 > Range 4 (unidirectional flow, multiple ranges)
* Range 1 > Range 2, Range 3 > Range 4 (bidirectional flows, multiple ranges)
If you try to SCI the ranges not conforming to the above, the following message
appears:
♦ M U L T I R N C E R R
Try again to set the ranges as .specified above.
■ 'I'ota I izat i on count i ng ra le
If you have changed the span while the counting rate is set for totalization, the
counting rale for 1(X)% output may have exceeded the maximum counting capacity.
In this kind of event, the following message appears and the sy.siem goes to the
counting rale setting sequence.
♦ H. OVER : RATE or L. OVER C RATE
Set the counting rate (See S.2.1 (/"Counting Rale’')for the newly set span*
