機器の改善により、太陽光発電コストが低下、FLUKE376 True RMS
Troubleshooting 4 to 20 mA (milliamp) process control systems without breaking the loop using Fluke 773 Milliamp Process Clamp Meter
Early reports from the field suggest that the new Fluke 772 and 773 Milliamp Process Clamp Meters may be game changers, breaking new ground for technicians in the HVAC controls industry. With the feature sets these meters offer, troubleshooting of the most common problems in modern control systems becomes a snap.
Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable and other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/deenergizing it.
Fluke 393 FC ソーラー・クランプ・メーターは、ソーラー・システムの設置、監視、テストに不可欠のツールです。ソーラー設備を含む CAT III 環境に適するよう、CAT III 1500 V/CAT IV 600 V の定格を有しています。
On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage current can cause unnecessary and intermittent tripping. In extreme cases, it can cause a rise in voltage on accessible conductive parts.
How to measure current with a digital multimeter plus clamp accessory.
Since a small increase in current flow to a motor produces a proportionately larger amount of heat, motor amperage exceeding nameplate values should be carefully investigated as a possible cause. These overload trips, though often caused by motor loading issues, can also indicate bearing failure, insulation breakdown or voltage unbalance.
Learn why on all current clamps and current clamp accessories, there is an arrow placed close to the beak or inside the beak opening.
MacDonald-Miller standardized on the Fluke 902 Clamp Meter when it came out several years ago.
Accessory current clamps expand a multimeter's flexibility and measurement capabilities by allowing it to measure up to thousands of amps.
The safety rated Fluke T+Pro gets field-tested by non-electricians. Larger buttons for gloved hands and a battery life indicator helped to make the transition from the old solenoid-based testers to the T+Pro much easier.
