Features & Applications:
Confidently take reliable readings with the Fluke 355 True-RMS Clamp Meter. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications. The extra rugged design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user protection when taking high-powered measurements. Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. It also measures voltage and resistance, making this an ideal clamp meter for utilities, electrical contractors and industrial service technicians.
Features:
- Reliably handle a wide range of high-current applications with 2000 A ac + dc true-rms, 1400 A ac and 2000 A dc
- The large 58 mm (2.3 in) jaw capacity is suitable for large or multiple conductors
- CAT IV 600 V, CAT III 1000 V rating for added user protection
- In-rush current measurement captures 'power-on’ surge current with accuracy and repeatability
- High voltage measurement of 1000 V ac + dc true-rms, 600 V ac, and 1000 V dc allows the user to perform multiple tests with only one tool
- Resistance to 400K ohms coupled with a continuity beeper provides the convenience of a multimeter in a clamp meter
- Accurately measure frequency up to 1 kHz for optimum troubleshooting
- Quickly analyze readings using the MIN, MAX, and AVG functions
- A large backlit display allows for easy visibility in low-lit areas
- Use the display hold feature to capture readings even when the display cannot be viewed
- Use the low-pass filter to smooth out noisy loads and stabilize readings
- Includes:
- 355 clamp meter
- C43 Soft carrying case
- 6 AA batteries
- TL224 1.5 m silicone rubber test leads
- TP2 Test Probes
