Firmware Patch Notes

Removal of Low side Pressure readings: The main display will now show "0.0" PSID if the Low side of the sensor is exposed to a greater pressure than the High side of the sensor. Previous firmware versions display the absolute value of the pressure differential in all situations. This change was made to avoid confusion if the MAKO gauge was connected to a backflow prevention assembly incorrectly. 

• Ex. 50 psi is applied to the high side and 55 psi is applied to the low side of the gauge. 

FW v 11 will display 5.0 PSID

FW v 13 will display 0.0 PSID

Rate of Change Graph re-scaled: The chevrons of the rate of change graph were modified to provide better feedback to the user in ranges seen during typical testing. The first chevron will now turn on when the pressure is changing at a rate of 0.1 PSID/sec. The last chevron will now turn on when the pressure is changing at a rate of 1.5 PSID/sec.

Other: Minor bug fixes and user improvements for the Calibration Adjustment process.  Even greater accuracy when measuring street (line, supply) pressures.
