General Notes for using the IM-SG
The Off button - Hold for 3 seconds to put the IM-SG to
sleep
The On button - Hold for 1 second to wake the IM-SG
When the IM-SG is powered up, it will display the condition
of the 9V battery. It has 3 different messages depending on
the condition of the battery.
Battery Good - The battery's voltage is greater than 7.2
Volts.
Battery Low Replace Soon - The battery's voltage is
between 6.4 Volts - 7.2 Volts.
Battery Bad Replace Now* - The battery's voltage is below
6.4 Volts and accuracy cannot be guaranteed.
* The accuracy of the IM-SG is not affected by the condition
of the battery unless the battery voltage is below 6.4 Volts.
In this case, it will not proceed to boot up, but instruct the
user to replace the battery instead. This insures accuracy
at all times.
Range button* - Press to cycle through the modes
(Low Range > High Range > Pink Noise)
Low Range = approximately 8 Hz - 600 Hz
High Range = approximately 600 Hz - 20 kHz
Pink Noise = All frequencies from 20 Hz - 20 kHz
* The Range button only cycles through the modes if the
impedance being measured is over 0.50 ohms.
