Heath Consultants Heath Volume Corrector (HVC) - Manual (Page 14)

14
* Uncorrected Volume/ Leading blanks or Leading zeros = Sets either “Leading Blanks” or “Leading
Zeros” on the LCD.
* Meter Factor = (Manual entry) Applies a correction factor to the input pulse count. This can correct for
a “Known and predictable” meter error. Allowable range is .95 to 1.05 (+ or – 5%).
* Turbine K Factor = (Manual entry) Allows entering a K factor from an electronic turbine meter
(Currently this option pcboard is not available at this time).
* Turbine Divisor = Used as a divider for the “Turbine K factor” (not currently used).
* Base Pressure = (Manual entry) Sets the Base Pressure used in the Correction Factor calculation. Note:
Do not type “PSIG” next to the entry.
* Zone Pressure = (Manual entry) Same as “Atmospheric Pressure” used in the Correction Factor
calculation. Note: Do not type “PSIG” next to the entry.
* Base Temp = (Manual entry) Sets the Base Temp used in the Correction Factor calculation. Note: Do
not type “DegF” next to the entry.
* Specific Gravity = Sets the “Specific Gravity” value of the gas for NX-19. Note: Do not type “mol %”
next to the entry.
* Percent Carbon Dioxide = (Manual entry) Sets the “% Carbon Dioxide” value of the gas for NX-19.
Note: Do not type “mol %” next to the entry.
* Wakeup Method = (Once Per Rev or Once Per Min) Sets the interval when all sensors are read and
LCD is updated. “Once per rev” is most common, however, if a meter is turning faster than 1 rpm it is
recommended to change to “Once per Minute” to keep the battery life within 4 years.
* Meter Rotation= (Counter Clockwise, Clockwise or Heavy Duty Index). This option should only be
used with optical indexes. Set to “Clockwise” or HD Index ONLY- when using “optical” input
(regardless of meter rotation). Note: “Heavy Duty Index” is the same as “Clockwise”. Note 2: This value
is not in use for “Falling magnet/ reed switch indexes which are standard in the HVC (It is grayed out).
* Meter Speed = (Slow (15 RPM Maximum) or Fast (120 RPM Maximum)). This value is not in use for
“Falling magnet/ reed switch indexes which are standard in the HVC (It is grayed out). This should only
be used with optical indexes. Note: Set to “Fast” will reduce the main battery life to 3 years. Set to
“Slow” or selecting “Digital” will allow up to 4 years of main battery life.
* Pressure Mode = (Auto or fixed). Use “Auto” when using live pressure input. Use “Fixed” when using
fixed factor measurement or there is a need to lock in a pressure reading used for pressure calculation.
* Temp Mode = (Auto or fixed). Use “Auto” when using a live Gas Temp probe input. Use “Fixed”
when using fixed factor measurement or there is no temperature probe connected. This fixed value will be
used for the Temperature part of the calculation.
