sp_volume_total_text 40A2 Vol totl text A 1 to 4 character description of a special unit of volume, which is based on the special unit of flow to represent total. 读/写 ASCII 2048
fixfreq 40A3 固定频率 A value (in Hertz) that will be indicated on the frequency output for the purpose of a loop test. 读/写 浮点 4096
totctl 40A4 累加器控制 Allows the user to Reset, Stop, or Start all totalizers. NOTE - Inventory totals are NOT reset. 读/写 枚举 4096
dencal 40A5 密度标定系数 14 characters describing the sensitivity of the sensor to density. 读/写 ASCII 32
max_zero 40A6 Zero time The number of readings collected from the sensor during an Auto Zero operation. 读/写 无符号 4
conv_lim 40A7 Converg. limit A unitless number that allows the user to reject the Auto Zero operation if the standard deviation is greater than 10 times the programmed convergence limit. A convergence limit of zero disables this feature. 读/写 浮点 16
pulse_width 40A8 Max pulse width For the RFT9739, a programmable time period, in seconds, that defines the crossover frequency for the frequency output, where Crossover freq. = 1 / (2 x Pulse width). Below the crossover, the output has a constant ON state, and an OFF state that varies with frequency. 读/写 浮点 512
control 40A9 Control output An output that produces 0 V ON and 15 OFF digital levels. The control output can represent faults, zero in progress, flow direction, event 1 or event 2. 读/写 枚举 1024
tempcal 40AA Temp cal factr A 14-character factor that describes the slope and offset of the linear output representing flow tube temperature. 读/写 ASCII 32
rt_zero 40AB 归零 A value, in microseconds, representing the phase shift between velocity signals from the sensor when measuring zero flow. 读 浮点 2
