3.1. Before you start
Open the cover on the bottom panel of the tester. Install four fully charged 1.2V Ni-MH
(or four 1.5V alkaline) batteries, watching the polarity.
Do not:
– mix new and old batteries;
– use batteries of different types at the same time;
– overheat or disassemble batteries;
– short-circuit batteries;
– try to re-charge alkaline batteries.
To charge Ni-MH batteries, use charging adapters recommended for this type of
batteries.
Any leaks of electrolyte from the batteries may seriously damage the tester.
Remove batteries if the analyzer is not being used for a long time. Store batteries in a
dry cool place.
3.2. Turning the tester on and off
To turn the tester on or off, use the power button
, located at the bottom left corner
of the keypad. When this button is pressed, firmware version number as well as battery
voltage are displayed on the LCD.
The on-screen menu system of the RigExpert IT-24 provides a simple but effective way
to control the entire device.
