374 and 375 True-rms AC/DC Clamp Meters Work horse clamps with increased performance and efl xibility Technical Data The new Fluke 374 and 375 clamp meters offer improved Measurement capability performance perfect for many current measurement situa- 600 A ac and dc current tions. With true-rms ac voltage and current measurements, measurement with fi xed jaw the Fluke 374 and 375 can read up to 600 V and 600 A in 2500 A ac current mea- surement with iFlex both ac and dc modes. Additionally, both are compatible with fl exible current probe (sold the new iFlex efl xible current probe (sold separately) which separately) expands the measurement range to 2500 A ac and pro- 600 V ac and dc voltage vides increased display efl xibility, ability to measure around measurement awkward sized conductors and improved wire access. True-rms ac voltage and current for accurate measure- ments on non-linear signals Frequency measurement to 500 Hz with both jaw and iFlex (Fluke 375 only) Resistance measurement to 60 k (Fluke 375) or 6000 (Fluke 374) with continuity detection Min, max, average and inrush recording to capture varia- tions automatically 500 mV dc measurement range to interface with other accessories (Fluke 375 only) 1000 F capacitance measurement Features iFlex fl exible current probe expands the measurement range to 2500 A ac while providing increased display fl exibility, ability to measure awkward sized conductors and improved wire access CAT IV 600V, CAT III 1000 V safety rating Integrated low pass fi lter (Fluke 375 only) and state of the art signal process- ing allows for use in noisy electrical environments while providing stable readings C US Proprietary inrush measure- Large, easy to read, backlight ment technology to fi lter display automatically sets the Ordering information out noise and capture motor correct measurement range 374 True-rms AC/DC starting current exactly as the so you do not need to change Clamp Meter circuit protection sees it switch positions while taking 375 True-rms AC/DC Ergonomic design fi ts in your a measurement Clamp Meter hand and can be used while Three-year warranty wearing personal protective Soft carrying case Optional accessories equipment i2500-10 iFlex Flexible Current Probe, 10 inches Specicfi ations i2500-18 iFlex Flexible Current Probe, 18 inches Fluke 374 and 375 Range Max Resolution Accuracy AC current via jaw 600 A 0.1 A 2 % 5 digits AC current via iFlex (optional) 2500 A 0.1 A 3 % 5 digits DC current 600 A 0.1 A 2 % 5 digits AC voltage 600 V 0.1 V 1.5 % 5 digits 0.1 mV (375) DC voltage 600 V 1 % 5 digits 0.1 V (374) 60,000 (375) Resistance 0.1 1 % 5 digits 6000 (374) Frequency (375 only) 500 Hz 0.1 Hz 0.5 % 5 digits Capacitance 1 F to 1000 F 1 F 1 % 4 digits True-rms Continuity Hold Backlight Min/Max Inrush Low pass filter Fluke 375 only 18 in iFlex Flexible Current Probe Optional accessory 10 in iFlex Flexible Current Probe Optional accessory Wire capacity 750 MCM or 2-500 MCM Safety rating CAT III 1000 V, CAT IV 600 V Models Feature Changes Old model: Fluke 337 New model: Fluke 376 Includes all 337 features plus: mV dc CAT IV 600 V, CAT III 1000 V 60 k iFlex 2500 A ac 1000 F 1000 V ac/dc Old model: Fluke 336 New model: Fluke 375 Includes all 336 features plus: 60 k CAT IV 600 V, CAT III 1000 V 1000 F Optional iFlex 2500 A ac Min/Max/Avg Fluke.
