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.
