produces a more stable reading as more cycles are averaged, but slows down 
the  update  rate.  At  very  low  frequencies,  the  update  rate  of  the  meter  is 
controlled  by  the  period.  In  totalizing  mode,  the  gate  is  always  open,  but  the 
gate time setting still determines the update rate of the meter. See also

 or 

Time before zero output

Hysteresis, Band 

 

A band in counts which controls relay action 

symmetrically  around  a  setpoint.  The  relay 
closes  (or  opens)  when  the  reading  goes 
above the setpoint plus one hysteresis limit, 
and  opens  (or  closes)  when  the  reading 
falls below the setpoint less one hysteresis 
limit. A narrow hysteresis band can be used 
to minimize relay chatter. A wide hysteresis 
band  can  be  used  for  control  applications. 
The  hysteresis  band  will  be  equal  to  two 
hysteresis limits. 

Hysteresis, Split 

 

Split hysteresis, where the setpoint is at the center of a symmetrical hysteresis 

band, is an alternative to span hysteresis. 

 Item #

 

Also  called  Display  Item.  A  numerical  value  in  the  meter  available  for  display 

under control of a front panel key or serial communications. For example, in the 
A+B totalizer mode, the sum of A+B is Item #1, Total A is Item #2, and Total B 
is  Item  #3.  When  the  meter  is  reset,  Item  #1  is  always  displayed.  To  view 
another  Item,  press  the 

RESET

  key.  For  Item  1,  the  yellow  View  “V”  LED  is 

unlit. For Item 2, the “V” LED is lit. For Item 3 the “V” LED flashes. 

Menu mode

  Meter programming mode used for input and range selection, setup, and confi-

guration.  Entered  into  from  the  Run  mode  by  pressing  the  MENU  key.  The 
Menu  mode  can  be  locked  out  completely  by  a  jumper  on  the  power  supply 
board. 

Meter Hold 

A rear panel input which freezes the meter display and all meter outputs while 

that input is tied to logic ground by a switch or is held at 0V (logic level true). 
The  meter  will  resume  operation  when  the  input  is  disconnected  or  is  held  at 
+5V (logic level false).  

Moving average filter 

 

A  digital  filter  mode  which  displays  a  weighting  moving  average  of  readings. 

Eight  moving  average  modes  are  selectable  with  the  following  equivalent  RC 
time constants: no filter, 0.1 sec, 0.2 sec, 0.4 sec, 0.8 sec, 1.6 sec, 3.2 sec, 6.4 
sec. 

Multiplier 

A  constant  multiplier  from  0.00001  to  100000  (in  decade  steps)  that  is  com-

bined  with  a 

scale  factor

  from  0.00000  to  9.99999  (fixed  decimal  point  and 

settable digits) to go from frequency in Hz to rate in engineering units such as 
gallons  per  minute  or  from  pulse  counts  to  total  in  engineering  units,  such  as 
gallons.  The  combination  of  a  6-digit  scale  factor  with  a  multiplier  provides
