IP-beskyttelsesklasser: En guide til IP-koder IP-koder (Ingress Protection) er en internasjonal standard (IEC 60529) som beskriver en enhets beskyttelsesgrad mot inntrenging av faste partikler og væske. Koden består av bokstavene IP etterfulgt av to sifre. Første siffer: Beskyttelse mot faste partikler Det første sifferet i koden angir beskyttelsesnivået mot tilgang til farlige deler og mot inntrenging av faste fremmedlegemer. Kode Beskyttelse mot faste partikler IP0X Ingen beskyttelse. IP1X Beskyttelse mot faste objekter større enn 50 mm (f.eks. en hånd). IP2X Beskyttelse mot faste objekter større enn 12,5 mm (f.eks. en finger). IP3X Beskyttelse mot faste objekter større enn 2,5 mm (f.eks. verktøydel). IP4X Beskyttelse mot faste objekter større enn 1 mm (f.eks. ledning). IP5X Støvtett; begrenset inntrengning av støv tillatt. IP6X Fullstendig støvtett; ingen inntrengning av støv. Andre siffer: Beskyttelse mot vann Det andre sifferet beskriver enhetens beskyttelse mot skadelig inntrenging av vann. ...

A Comprehensive Guide to the ZL128B Digital Multimeter The ZL128B Digital Multimeter is a versatile and user-friendly tool designed for professionals, hobbyists, and DIY enthusiasts. With its 9999-count LCD color display, USB charging capability, and wide range of measurement functions, it stands out as a reliable device for electrical testing, automotive diagnostics, and more. In this blog post, we’ll explore: ✔ Key features of the ZL128B ✔ A detailed table of its capabilities ✔ How to use it effectively Key Features of the ZL128B Multimeter High-Resolution Color Display – The 9999-count LCD screen with adjustable backlight ensures clear readings in various lighting conditions.

Built-in USB Rechargeable Battery – Unlike models requiring AAA batteries, the ZL128B has a built-in 1000mAh battery for convenience. Non-Contact Voltage (NCV) Detection – Safely detects live wires without direct contact. Compact & Portable – Lightweight (280g) with a carrying case for easy transport. Additional Functions – Includes temperature measurement (-50°C to 1100°C), diode testing, continuity check, and a flashlight. ZL128B Capabilities Overview Function Range/Specifications Notes DC Voltage 0V–1000V (Auto/Manual) High accuracy for electronics & auto AC Voltage 0V–750V (Auto/Manual) True RMS support (0–1kHz) DC/AC Current 0mA–10A Supports automotive diagnostics Resistance 0Ω–100MΩ Useful for circuit troubleshooting Capacitance 0–6mF Tests capacitors in electronic repairs Frequency 0–10MHz For signal analysis in circuits Temperature -50°C to 1100°C (Probe) / 0°C–60°C (Ambient) Includes a temperature probe NCV Detection Live wire detection without contact Enhances safety Diode Test Yes Checks semiconductor functionality Continuity Test Audible beep for closed circuits Quick wire testing Battery Type Built-in 1000mAh (USB rechargeable) No need for disposable batteries How to Use the ZL128B Multimeter 1. Basic Setup Power On: Press the power button; the backlit LCD will activate. Select Mode: Rotate the dial to choose the desired function (e.g., voltage, resistance). Connect Probes: Insert the black probe into the COM port and the red probe into the appropriate jack (e.g., VΩ for voltage/resistance, 10A for high current). 2. Measuring Voltage DC Voltage: Set dial to V⎓, touch probes to the circuit (red to +, black to -). AC Voltage: Set dial to V~, place probes across the AC source. 3. Testing Continuity & Resistance Continuity: Set to continuity mode (⎓)), touch probes to wire ends—a beep confirms a closed circuit. Resistance: Set to Ω, place probes across a resistor (ensure power is off). 4. Checking Current DC/AC Current: Switch to A⎓ or A~, connect in series with the circuit (use the 10A jack for high currents). 5. Using NCV Detection Non-Contact Voltage: Hold the multimeter near a wire—an alarm or light indicates live voltage. 6. Temperature Measurement Insert the temperature probe into the designated port, touch the probe to the surface, and read the display. 7. Auto Power-Off & Data Hold The ZL128B has auto power-off to save battery. Press HOLD to freeze readings for recording. Final Thoughts The ZL128B Digital Multimeter is an all-in-one tool for electricians, engineers, and DIYers. Its USB charging, wide measurement range, and safety features make it a top choice. Whether you’re troubleshooting a car, testing home circuits, or working on electronics, this multimeter delivers precision and convenience. ...

Optimizing your UniFi wireless network involves balancing coverage, speed, and interference. Below are key settings for both bands, including Multicast-to-Unicast configuration. 1. General Best Practices Band Steering: Prefer 5 GHz (Settings > WiFi > Band Steering). Disable Legacy Rates: Turn off 802.11b rates (1, 2 Mbps) (Settings > WiFi > Advanced > Data Rate Control). Airtime Fairness: Enable to prevent slow clients from hogging bandwidth (Settings > WiFi > Advanced). Minimum RSSI: Optional (e.g., -75 dBm for 2.4 GHz, -70 dBm for 5 GHz). 2. Band-Specific Tuning Setting 2.4 GHz Recommendation 5 GHz Recommendation Channel Width 20 MHz (never 40 MHz) 80 MHz (or 40 MHz if congested) Transmit Power Medium/Low High/Auto Channels 1, 6, 11 (manual scan) Non-DFS (36-48, 149-161) DTIM Period 3 (default) 3 (default) Fast Roaming - Enable 802.11k/v/r Notes Avoid DFS channels Some clients may not support fast roaming 3. Multicast-to-Unicast (Critical for Streaming/IoT) Enable Multicast Enhancement: Converts multicast traffic (e.g., Chromecast, Sonos) to unicast for reliability. Location: Settings > WiFi > [SSID] > Advanced > Multicast Enhancement. IGMP Snooping (Optional): Helps manage multicast groups efficiently. When to Use: ✔ Smart TVs (Apple TV, Roku) ✔ IoT devices (e.g., Sonos, VoIP) ✔ Video streaming (IPTV, AirPlay) ...

Run first installation as normal. When asked for country code, press SHIFT+F10, a command prompt should pop up. Enter: OOBE\BYPASSNRO Computer restarts. When asked to connect to internet, click on text left of the button, “I don’t have internet”.

Stumbled across this repo, not tested yet. Don’t know why use this instead of run package from nvidia. From Nvidia Github repo Note that the kernel modules built here must be used with GSP firmware and user-space NVIDIA GPU driver components from a corresponding 560.35.03 driver release. This can be achieved by installing the NVIDIA GPU driver from the .run file using the --no-kernel-modules option. https://www.nvidia.com/en-us/geforce/drivers/ sh ./NVIDIA-Linux-[...].run --no-kernel-modules Build and install: git clone https://github.com/NVIDIA/open-gpu-kernel-modules.git cd open-gpu-kernel-modules git checkout 560.35.03 make modules -j$(nproc) make modules_install -j$(nproc)
