Floor pump with G3 digital gauge

A. Basic operation

A. 1. Power on/Choose desired comparison memory

1.  All the way „did“ remember to power on the gauge first  

before engaging the pump head to the tire valve or refer A. 6.

2. Press and hold any key until seeing „on“ and a sound 

pattern of „Bi“ for 1 time can be heard.

3. Short press left-key each time to switch and check desired 

comparison memory from M1 to M4.

4. Long press left key to set desired comparison memory 

(Refer C.) for M1 to M4.

A. 2. Choose desired measurement scale

1. Press the right key each time to select desired scale from 

PSI, BAR Kg/cm

2

 to KPA.

A. 3. Pumping

1. Engage the right pump head to the tire valve.
2. Keep pumping and read the pressure.
3. Good pressure: when the pressure measured is equal to or 

within 15% higher than the selected comparison memory 
pressure a circle like   shows up to indicate the pressure 
is good and a sound pattern of „Bi-Bi“ goes on for 5 times.

4. Over Pressure: when the pressure measured is 15% over 

the selected comparison memory pressure, and a sound 
pattern of „Bi-Bi-Bi“ for 5 times can be heard.

NOTE:

a. In engaging status, the gauge won`t be going to auto-off.
b. Max pressure for this pump & gauge is l6Ops, damage 

maybe caused if over the limit. 

A. 4. Auto off/Manual off

1. With no further operation of pumping in 30-50 seconds then 

the gauge will power off Automatically with „Bi-Bi“ sound 
pattern.

and reload battery to reset everything back to factory 
default setting.

A. 6. Calibration

1. „ALI“ mode: Press both keys at the same time until seeing 

„ALI“ with 1 beep and a sound pattern of „Bi-Bi“ after 
release the keys. Another 2 beeps after callibrated.

2. Power on: Power on all the way will auto-calibration.

NOTE:

 

Calibration „must“ in disengaging status.

B. Battery replacement

tely 25 degrees to open it.

2. Since the battery is so tightly secured in the battery  

chamber a pin-like tool is helpful to normal.

3. M1 through M4 will be reset to the factory default setting.
4. Follow C. to enter your own settings.

C. Advanced operatlion

C. 1. Change setting of the comparison memory

1. The factory setting for Ml, M2, M3 and M4 are 35psi, 40psi, 

50psi, and 11Opsi respectlively.

2. Press and hold the left key until seeing „SET“ with 1 beep 

the memory pressure starts to blink.

3. Press left-key once to decrease the pressure valve by 1(For 

PSI or KPA) or 0.1 (For BAR or kg/cm2) right-key to increase.

4. After setting it goes back to the measuring mode auto-

matically in 4 seconds with 1 beep after no any further 
activation of measuring or key pressing.

C. 2. Function summary for right key long press

1. With gauge on, long press right key will have functions  

as follow: 
OFF (1 beep) – BLANK (2 beeps) – odE (3 beeps) 
OFF means power off manually (A.4.) 
BLANK (no function) 
odE means code version number
