CODE 62 - RATE A CONVERSION FACTOR
The Rate A Conversion Factor is used to convert Display A to indicate rate in
the desired time unit. See Appendix “F” - Scaling For Rate And Display C.
[62 1] Rate Per Second (x1)
[62 2] Rate Per Minute (x60)
[62 3] Rate Per Hour (x3600)
CODE 63 - RATE MINIMUM/MAXIMUM UPDATE TIME
The determination of the rate value uses a method in which the elapsed time is
measured between the first and last pulse of the update period. In the Display C
modes [41 2,3,4], the rate channels are synchronized. The slower of the two
channels will determine the minimum update time. The minimum update time is
the shortest the time period can be. Once the minimum update time has expired,
the unit will end the measurement period, for the synchronizing channel, when
the next negative going count edge occurs. If the unit does not receive the next
negative count edge within the maximum update time at the start of the
measurement period, the unit will end the time period and calculate the rate based
upon the amount of pulses received during the time period. After the
synchronizing channel ends its measurement period, the other channel will end
its measurement period when it receives the next negative going edge.
[63 1] 0.5 Sec. minimum/1 Sec. maximum
[63 2] 1 Sec. minimum/2 Secs. maximum
[63 3] 2 Secs. minimum/4 Secs. maximum
[63 4] 4 Secs. minimum/8 Secs. maximum
[63 5] 8 Secs. minimum/16 Secs. maximum (max. rate = 7500 cps)
[63 6] 16 Secs. minimum/32 Secs. maximum (max. rate = 3250 cps)
CODE 64 - RATE A SCALE MULTIPLIER
The Rate A Scale Multiplier is used in conjunction with the Rate Scale Factor
A and Rate A Conversion Factor to scale the actual signal input to obtain the
desired reading.
[64 1] x 1000
[64 2] x 100
[64 3] x 10
[64 4] x 1
[64 5] x 0.1
[64 6] x 0.01
CODE 65 - RATE A & B DECIMAL POINT & LEADING ZERO
BLANKING
There are six basic modes of decimal point placement for the Rate A & B
indicators of the Gemini 5200. The decimal point is placed to the right of the
display digit that corresponds to the mode identifier. (The right most decimal point,
digit 1, is never turned on.) A “-” sign in front of the mode identifier will inhibit
leading zero blanking. The absence of a “-” sign will enable leading zero blanking.
