The ADS Mikron is a high performance, simple-to-use leak 
locator. The design is based upon an advanced sensor 
and incorporates low-noise processing electronics to give 
excellent acoustic performance over a wide frequency 
range. Mikron incorporates a Minimum Noise Level 
measurement system.

Operation of the ADS Mikron Leak Locator
Mikron
Connectors
Plug the sensor into the top right-side socket of the 
amplifier. The sensor must only be connected or 
disconnected whilst the amplifier is turned off. This socket 
is also used for the battery charging.
The left-side socket is used to connect the headphone.
Switch-on and Off
To turn the amplifier on, press any key until it turns on. (The sensor and headphones must be connected before the amplifier is 
switched on). 
To turn the unit off, press the ‘Increase’ and ’Decrease’ buttons together. The amplifier will switch off automatically if no button is 
pressed for 5 minutes.

When pressed the current minimum noise level is shown in the right 
(largest) box and sound is available in the headphones. When released \
the minimum value in the right box is held in memory.
                                                                        \

This button is used to decrease the volume in the headphones, or adjust \
the screen contrast in screen contrast mode.
Increase                                                                \
                                                                       
This button is used to increase the volume in the headphones, or adjust \
the screen contrast in screen contrast mode.
Store 
When pressed and released, the current value of the minimum sound 
level (shown in the right hand box) will be stored in the middle box a\
nd 
the contents of the middle box moved to the left box. The contents of th\
e 
left box are discarded. This feature allows the last 3 saved values to b\
e 
shown on the screen. Holding the store button for about 3 seconds will 
delete the displayed data in the boxes.
Filters 
When pressed and released, the filter selection will cycle through the 
options. When a new filter is selected the amplifier takes a few seconds\
 to 
stabilize. If the Press-to-listen button is pressed at this time the sou\
nd 
level figure will flash to indicate it is unreliable. 
						

							Minimum Noise Level Display
To enable accurate leak pinpointing, Mikron displays the Minimum Noise Level 
and also the two previous Minimum Noise Level measurements such that the 
user can easily tell whether they are moving toward or away from the leak.
The main display area has three boxes. When the amplifier is switched on 
these boxes are empty. When the Press-to-listen button is pressed, the current 
Minimum Noise Level is shown in the right hand (largest) box. When the 
Press-to-listen button is released, the current level in the right box is displayed 
permanently. Each time the store button is pressed, the values move to the 
left and the right-side value is cleared (the left-side stored value is lost).  In this 
way the latest displayed value can be easily compared with the two previous 
values.
The left side of the display shows a speaker symbol when the Press-to-listen 
button is held down. When not pressed, the symbol is crossed out. 
Sound Volume Display
A triangle graph display representing the volume of the sound in the headphones is shown below the speaker symbol. When the unit 
is turned on, the minimum volume is set in the headphones, this can be changed using the decrease and increase buttons. Changing 
the volume in the headphones does not change the noise level displays.
Real-Time Noise Level
Real-Time Noise Level shows an analogue bar of the current sound level 
detected in the sensor, i.e. not the Minimum Noise Level.
Filter Display
The lower part of the display shows the selected filters. In the example below, the filters have been set to allow a listening range of 
75Hz to 1500Hz. Filter selection is made by pressing the filter button. The following filter ranges are available:
Backlight
To turn the backlight on or off, hold the filter button for more than two seconds. Each time the button is held the backlight will cycle 
through on and off.
Contrast
Enter contrast mode by pressing the store and filter buttons together. To adjust the contrast press the decrease and increase buttons 
as required. When the desired level has been set press the filter button to return the unit to normal operation.
Battery and Charging
The amplifier contains a non-removable, rechargeable battery. Typical battery life is 35 hours use with the backlight off and 17 hours 
with the backlight on.  The battery display shows the current charge of the battery.
To charge the battery the battery charger is connected to the amplifier unit (right hand connector) and plugged into a suitable 
electrical outlet power supply.
