Multi-purpose Precision Test Pen What it does Precision test pen designed for accurate measurement on PCB circuits and for mini capacitance measurements, with particular focus on chip (on-board) capacitance testing. Multifunctional tool for quick, one-handed testing during assembly, repair, and troubleshooting. Key benefits Accurate diagnostics: precision measurement capability helps locate faults and verify component capacitance without removing parts from the board. Safe to use: rated for safety up to 250 V, providing protection for common low-voltage electronics work. Fast and convenient: single-handed operation speeds up inspections and repetitive measurements in tight spaces. Versatile application: built for small-capacitance and chip-level measurements where standard probes may be too large or imprecise. Important attributes Function: precision circuit testing and mini capacitance measurement, optimized for chip capacity testing on PCBs. Compatibility: suitable for use directly on PCB circuits and on-board chip capacitors; designed for applications that require fine, localized measurement. Operation: one-handed, multifunctional test use that simplifies field and bench work. Performance: engineered for precise, repeatable readings in miniature circuit contexts. Build: designed for reliable everyday use in electronics diagnostic workflows. Practical use scenarios 1. PCB troubleshooting: quickly probe traces and components on a populated PCB to isolate faulty sections without desoldering parts. 2. Component verification: measure small capacitances of chips and surface-mounted capacitors during repair or quality checks to confirm correct values. 3. Field service and assembly: perform fast, one-handed tests on electronic modules during assembly line checks or on-site repairs where speed and access are limited. How it helps Reduces time spent disassembling boards for component testing by enabling on-board measurements. Minimizes risk of damage during inspection with a tool designed for chip-level precision and a 250 V safety rating. Improves workflow efficiency with multifunctional, single-handed operation suited to tight or awkward test points. Usage tips Use steady contact on the test point for best measurement consistency. Follow standard safety practices for working on powered circuits within the pen’s rated voltage limits (up to 250 V).
