E&OE Overview Versatile and rugged clamp meter for high currents Confidently take reliable readings with the True RMS Fluke 355 digital clamp meter, the tool of choice for high current clamp-on amp meter measurement up to 2000 A. 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. The 355 also measures voltage and resistance, making this an ideal clamp meter for utilities, electrical contractors and industrial service technicians. Easy to use all-in-one tool 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 provide 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 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 Specifications Electrical Specifications Current measurement AC 10 Hz to 100 Hz Range 40 A / 400 A / 1400 AC rms Resolution 10 mA / 100 mA / 1 A Accuracy 40 A: 1.5% rdg + 15 digits 400 A: 1.5% rdg + 5 digits 1400 A: 1.5% rdg + 5 digits Trigger level for Inrush 0.50 A / 5.0 A / 5 A Trigger level for Hz filter OFF 2.50 A / 2.5 A / 8 A Trigger level for Hz filter ON 0.50 A / 2.5 A / 8 A Crest Factor (50/60 Hz) Range 40 A / 400 A / 1400 AC Crest Factor1 2 @ 33 A, 2.4 @ 27 A2 @ 330 A, 2.4 @ 270 A2 @ 1000 A, 2.4 @ 833 A Current measurement AC 100.1 Hz to 1 kHz Range 40 A / 400 A / 1400 AC rms Resolution 10 mA / 100 mA / 1 A Accuracy 40 A: 3.5% rdg + 15 digits 400 A: 3.5% rdg + 5 digits 1400 A: 3.5% rdg + 5 digits Trigger level for Inrush 0.50 A / 5.0 A / 5 A Trigger level for Hz filter OFF 2.50 A / 2.5 A / 8 A Trigger level for Hz filter ON 0.50 A / 2.5 A / 8 A Current measurement DC Range 40 A / 400 A / 2000 A Resolution 0.01 A / 0.1 A / 1 A Accuracy 40 A: 1.5% rdg + 15 digits 400 A: 1.5% rdg + 5 digits 2000 A: 1.5% rdg + 5 digits Voltage measurement AC 10 Hz to 100 Hz(600 V range has 10% over range to 660 V) Range 4 V / 40 V / 400 V / 600 V AC rms Resolution 1 mV / 10 mV / 100 mV / 1 V Accuracy 4 V: 1% rdg + 10 digits 40 V: 1% rdg + 5 digits 400 V: 1% rdg + 5 digits 600 V: 1% rdg + 5 digits Trigger level for Hz filter OFF 0.25 V / 6 V Trigger level for Hz filter ON 0.25 V / 6 V Voltage measurement AC 100.1 Hz to 1 kHz(600 V range has 10% over range to 660 V) Range 4 V / 40 V / 400 V / 600 V ac rms Resolution 1 mV / 10 mV / 100 mV / 1 V Accuracy 4 V: 3% rdg + 10 digits 40 V: 3% rdg + 5 digits 400 V: 3% rdg + 5 digits 600 V: 3% rdg + 5 digits Trigger level for Hz filter OFF 0.050 V / 0.25 V / 6 V / 6 V Trigger level for Hz filter ON 0.050 V / 0.25 V / 6 V / 6 V Voltage measurement DC Range 4 V / 40 V / 400 V / 1000 V Resolution 0.001 V / 0.01 V / 0.1 V / 1 V Accuracy 4 V: 1% rdg + 10 digits 40 V: 1% rdg + 5 digits 400 V: 1% rdg + 5 digits 1000 V: 1% rdg + 5 digits Resistance measurement Range 400 Ω / 4 kΩ / 40 kΩ / 400 kΩ Resolution 0.1 Ω / 1 Ω / 10 Ω / 100 Ω Accuracy 1.5% + 5 digits Continuity beeper On at ≤ 30 ΩOff at ≥ 100 Ω Frequency measurement Measurement range 5.0 Hz to 1 kHz Resolution 0.1 Hz (15 Hz to 399.9 Hz); 1 Hz (400 Hz to 1 kHz) Accuracy – 5.0 Hz to 100 Hz 0.2% + 2 counts Accuracy – 100.1 Hz to 1 kHz 0.5% + 5 counts Trigger level Refer to current and voltage tables 1.
