Turn the dial to a higher voltage setting - Try the “200” setting in the DC voltage (V⎓) section. This will handle voltages up to 200V. Check your connections - Make sure: The black probe is firmly in the “COM” port The red probe is firmly in the “VΩmA” port You’re making good contact with the battery terminals Verify the battery orientation - Make sure you’re touching: Black probe to the negative (-) end of the battery Red probe to the positive (+) end of the battery

Iceraven and IronFox are both open-source browsers for Android, each offering privacy and customization features but with different emphases and user audiences. Core Features Feature Iceraven IronFox Privacy & Telemetry Reduced telemetry, customisable123 Strongly privacy-hardened, all telemetry removed456 Add-ons/Extensions Extensive support, larger list than stock Firefox178 Supports Firefox Android extensions6 Customization About:config, more desktop-like options127 Advanced privacy defaults, stripped-down interface456 Speed & Performance Comparable to Brave/Chrome; resource-optimised89 Lightweight, slightly faster than stock Firefox6 Main Focus Customization, extension and power-user features12 Privacy, de-bloated and anti-tracking465 Updates Community-driven, slower but steady210 Active, responsive to user issues54 Official Channels Github APK releases, not on Play Store128 F-Droid/Accrescent, Github, not on Play Store46 Iceraven Browser Built on stable Firefox for Android, with a focus on more add-on availability and configuration options like about:config1112. Appeals to users who want to replicate desktop Firefox’s customization and plugin experience on mobile111. Releases and updates are maintained via Github and aren’t distributed via the Play Store128. Some comments note the lack of warranties or guarantees for security; best used by power users familiar with browser internals12. IronFox Browser Derived from Mull (itself a privacy-focused Firefox fork), with aggressive tracking and telemetry removal456. Prioritizes user privacy, blocks telemetry by default, and comes with strict tracking-protection settings46. Keeps features like Firefox Sync; disables or restricts features leaking data (such as WebGL, unless manually enabled)46. Distributed via alternative app stores like F-Droid, Accrescent, and Github; not available on Play Store46. Some advanced privacy features may result in compatibility issues with certain websites, especially those relying on features IronFox disables by default4. Summary Iceraven is ideal for those wanting a “power-user” browser with deep customization and a broad add-on library, making it similar to desktop Firefox in spirit1117. IronFox is best for users who place privacy first, seeking a Firefox-based browser that automatically strips out telemetry and unnecessary features for a lightweight, secure experience54612. Both offer more control and privacy than standard Firefox for Android, but Iceraven focuses on flexibility while IronFox focuses on privacy hardening. 1314151617181920 ...
