MK5 Display Details 

   

A. Rate of Change Graph:

 Tells you how quickly the measurement is changing. When a reading is 

stable, the bar will have a single dot in the middle. See the Rate of Change Graph section for more 
details on how this feature is used. 

B. Main Display:

  Shows the current, live reading from the differential pressure sensor. 

C. Captured Value:

 Up to six captured values can be stored in positions 1-6. These readings can be 

cleared individually or all at once at any time. See the Capture and Clear Values section for more 
details. 

D. Active Position Cursor:

 Shows you to which position the next Captured Value will be saved. 

E. Auto Power Off (APO) indicator:

 The Mako is set to automatically power off after 30 minutes of 

no use. This conserves power and saves you batteries if you forget to turn MAKO off between 
uses.  

F. Calibration (CAL) Mode indicator

: Shows when the unit is in calibration mode.  

G. Download Indicator:

 Shows when a firmware update is being downloaded into MAKO. 

H. Wireless Connection Indicator

: Shows that the Mako has a Bluetooth connection to a mobile 

device.  

I. Battery Life Indicator

: Shows the approximate battery life remaining. When the battery reaches 

zero bars, the empty battery icon will begin to blink alerting you that the batteries should be 
changed. When the battery life is critically low, a warning tone will sound before the unit shuts 
down. 

J. Units

: Shows the pressure units currently being displayed. There are two possible pressure 

differential units, PSID and KPaD.  

K. Captured position ID

: Label for the Captured Value or Capture Position adjacent to the ID
