MediaGauge™ (Model MG-9V) Digital Pressure Gauge  
Product Overview  
Product Description  
The MediaGauge™ Model MG-9V digital pressure gauge is  
a stand alone 9V battery operated multi-functional digital  
pressure gauge. The MG-9V digital pressure gauge  
contains a media isolated piezoresistive pressure sensing  
element, signal conditioning circuitry for temperature and  
calibration compensation, a 304L stainless steel input  
pressure port and a LCD back lit display. The MG-9V digital  
pressure gauge has an accuracy of ± 0.25 % full scale. A  
battery power saver mode is incorporated into the MG-9V to  
automatically shut the LCD display off after 5 minutes  
prolonging the battery’s life.  
The MediaGauge™ MG-9V digital pressure gauge comes  
standard with a variety of keypad operated functions –  
multiple pressure unit display reading (PSI, BAR or MPA);  
memory storage of maximum peak pressure reading; and  
zero adjustment. A Ft of Head pressure measurement  
display is available as an option for the MG-9V model.

The MediaGauge™ MG-9V digital pressure gauge is made  
of all laser-welded 304L & 316L stainless steel for optimal  
media isolation and usage in a wide variety of media. These  
compact 3 inch, robust gauges measure pressures from  
5 PSI to 5000 PSI and are well suited for a variety of  
industrial and commercial applications such as refrigeration,  
compressors, pumps, hydraulics, pneumatics and waste  
water.

buttons  
ON/UNIT/OFF;  
Backlight/P-H (Peak-Held) and RESET/CLEAR.  
To turn the LCD backlight on: Press the Backlight/P-H  
button once. To turn the LCD backlight off: Press the button  
again.  
To see the maximum peak pressure the unit has measured:  
Press and hold down the Backlight/P-H button for 3  
seconds. The maximum pressure reading will be blinking.  
If the maximum pressure read was over the unit’s maximum  
pressure range, o.L will be blinking on the display.  
To return to the current pressure reading:  
Press the  
Backlight/P-H button and hold down for 3 seconds.  
The RESET/CLEAR button is used to reset the gauge to  
whatever pressure is currently applied to the port and to  
clear the stored maximum peak pressure reading.  
To reference your MediaGauge™ digital pressure gauge to the  
input port: Press and hold the RESET/CLEAR button for 3  
seconds. The MediaGauge™ MG-9V will now be reference  
to your input port. For example, if you have 20 psi on the  
display and then you press and hold the RESET/CLEAR  
The ON/UNIT/OFF button is used to display the  
pressure reading; switch between pressure units (PSI; BAR;  
and MPA) and to power down the unit.  
To power on the unit: Press the ON/UNIT/OFF button. The  
MediaGauge™ MG-9V has a battery saver mode and will  
automatically shut off the display after 5 minutes.  
button for 3 seconds the display will show 0.0 psi.  
A
measurement of 30 psi would then read as 10 psi on the  
display.  
To display the pressure reading in a different pressure unit:  
Continue to depress the ON/UNIT/OFF button until the  
arrow in the LCD points to the pressure units desired.  
To reset the MediaGauge™ digital pressure gauge: Make sure  
the input port is either disconnected or connected to a 0 psi  
input. Press and hold down the RESET/CLEAR button for 3  
seconds.  
To manually power down the unit: Press the ON/UNIT/OFF  
button and hold down for 3 seconds until OFF is displayed  
and then release the button.
