Usage Features:
The MSK 30/L is designed for intuitive operation with a combination of physical buttons, a navigation wheel, and a touch screen.
- Touch Screen Display Area: Displays signals, measurement parameters, image previews, and provides access to context-sensitive menus and transport stream information.
- Navigation Wheel: Used for navigating menu items, confirming selections, and changing setting values. It can also be pressed and held to open drop-down menus or numeric input fields.
- Numeric Field Input: Allows precise entry of frequency values and other numerical settings.
- Volume Menu: Adjusts volume, brightness, image format, and activates/deactivates battery saving mode.
- Configuration Menu: Provides access to advanced settings for SAT, TV, and CATV configurations, SAT Finder, SAT SCR, meter information, and diagnostics.

- SCR User Frequency: Allows configuration of SCR (Single Cable Routing) user frequencies, including LNB type and SCR user selection.
- Main Menu Access: Quick access to SAT, TV, CATV measurement ranges, spectrum analyser, channel lists, service functions, help, and memory.
- DC-RF In Switch: Controls remote feed voltage for LNBs. An LED indicates DC offset in SAT signals, prompting users to switch off the remote feed to prevent damage.
- Battery Status Indicators: Icons on the touch screen provide visual information about the battery charge level (FULL, <80%, <50%, <30%, <10%).
- Battery Saving Mode: Reduces display brightness after 30 seconds and automatically turns off the meter after 5 or 10 minutes of inactivity to conserve battery life.
- Dolby AC3 Audio Decoding: The device supports decoding of Dolby AC3 Audio code with an optional paid upgrade.
Maintenance Features:
- Cleaning: The meter should be cleaned with a soft cloth dampened with a solution of water or alcohol. Aggressive chemical products, diluting agents, abrasives, or rough cloths should be avoided.
- Battery Charging:
- Charge the battery at ambient temperature (approx. 20 °C) in well-ventilated areas.
- Do not cover the meter during charging or charge it in a hard-top case.
- Always turn off the meter to charge the battery.
- Charge for at least 7 hours overnight after each use, even if not fully discharged.
- Avoid leaving the battery discharged for extended periods to prevent premature failure.
- LED indicators (MAINS and CHARGE) provide feedback on the charging process (on/on for charging, on/off for completed, on/flashes for abnormal temperature).
- Battery Test:
- A battery test can restore the capacity of an old battery by performing 3 to 5 tests.
- Each test lasts approximately 20 hours, during which the meter cannot be used.
- The meter turns off automatically after the test.
- All functions except RESET are disabled during the test to ensure accuracy.
- The RESET function remains active for emergency shutdown.
- Interrupting the test with RESET may lead to incorrect battery charge display, requiring a retest.
- The battery is fully charged at the end of the test.
- Test results are displayed as a combination of letters and numbers (e.g., 130ACLY), where the number indicates battery life in minutes, and the last letter (Y/N) indicates working order or fault/interruption.
- Waste Disposal: Electronic equipment must be disposed of properly at an official collection point in accordance with directive 2002/96/EC.
