An analog multimeter can still be used to quickly check if a capacitor is shorted, open-circuited, or capable of charging and discharging. However, if precise capacitance measurement or an assessment of capacitor quality is required, a digital multimeter or LCR meter will yield more reliable results
By simply measuring the rotational speed (RPM) and comparing it against design specifications or historical maintenance data, engineers can detect signs of belt slippage, speed reduction, or power loss without needing to disassemble the motor
Measuring pump shaft speed helps determine the equipment's actual rotational speed (RPM), allowing for comparison against design specifications to detect issues such as belt slippage, incorrect gear ratios, abnormal motor operation, or failure to achieve the desired flow rate. Depending on operating conditions, engineers may choose a laser tachometer, a contact tachometer, or a stroboscope
RPM measurements can certainly be used to calculate conveyor belt speed (m/min) if the drum diameter is known. Learn about the calculation formula, practical examples, and how to take accurate measurements using a tachometer
The more high-capacity machinery a factory houses and the more complex its power supply network becomes, the harder it is for routine checks such as voltage measurements or visual inspections of electrical cabinets to fully reflect the safety status.
Frequently Asked Questions about using a multimeter: measuring current, selecting the measurement range, measuring diodes, MOSFETs, inverters, PLCs, and 4-20mA signals.
Automotive circuit boards, sensors, modules, and plastic components can all experience issues after repeated transitions between cold and hot environments. A thermal shock chamber operating from -40°C to +150°C enables the replication of these temperature fluctuations under controlled testing conditions.
An electronic component may operate stably under constant temperature conditions yet fail after repeated rapid transitions between hot and cold. The issue typically stems not from a specific temperature level, but rather from the rate of temperature change and the number of hot-cold cycles
Electrical safety is consistently one of the primary criteria evaluated before electrical or electronic equipment—or industrial components—are released to the market. A product may operate reliably yet still fail to meet requirements if its insulation lacks sufficient durability, its grounding resistance exceeds permissible limits, or leakage current occurs during operation.
When it comes to electrical safety testing equipment specifically Hipot testers—many QA/QC and testing engineers are familiar with the globally renowned brand Associated Research. A subsidiary of the parent company IKONIX, Associated Research (ARI) invented the world's first commercial Hipot tester.
