True RMS Clampmeter with NCV Detector

It can be very difficult to make accurate current and voltage readings in industrial and commercial applications when electronic devices are present. Fluorescent lights, motor drives, computer power supplies, and other electronic systems can distort the AC waveform, making it hard for averaging meters to get an accurate read. True RMS uses a more advanced formula to adjust for this kind of distortion. One important safety tool that is built in to the MA1500 is a non-contact voltage (NCV) detector. The detector quickly identifies the presence of voltage on live wires and alerts the user with a red LED indicator. For you, this eliminates the need for a separate tester, offering you more value, added safety, and less tool bag clutter. The MA1500 amp clamp has a CAT IV-600-volt overvoltage safety rating.

Other Features

The bright 5-digit, 40,000/4,000 count backlit display is complemented by several one-button functions including data hold, min/max, and two current ranges: 400 amp and 1500 amp. In addition, the jumbo 52mm jaw opening handles conductors up to 500 MCM. Besides electrical and electronic testing, you can capture temperature measurements using the Type K wire probe.

Extech 380941 AC/DC Mini Clamp Meter

Mike — Sun, 03 Apr 2016 01:51:57 +0000

Key Functionality of the Extech 380941

The 200A AC rating with 100mA resolution and 40A DC rating with 10mA (DC) resolution is optimized for finding problems where very low current variances would be missed by standard clamp meters. The meter doubles as a DMM with added resistance and frequency functions. Whether you are checking amp draws on commercial electrical circuits or troubleshooting relays on vehicle air conditioning systems, the go-anywhere 23mm jaw opening is compact enough to fit in tight locations.The 4-digit (4,000 count) readout is easy to read and a 40 segment bargraph helps simulate an analog display, better illustrating swings in readings. The Data Hold function freezes the display while the Min/Max function tracks and displays minimum and maximum values – useful for blind measurements and start-up draw. The zero function makes it easy to perform relative measurements.

Features

200A AC & 40A DC current readings
Data Hold, Min/Max and zero modes
Low current range & 10mA DC resolution
Also reads voltage, resistance & frequency
Ergonomic design & small 23mm jaw opening

Additional Features

Relative Measurements 1) Press the Zero key and the present measurement will Zero. 2) All subsequent measurements are displayed with respect to the zeroed reading. For example, if a 20A reading is zeroed and a 30A reading is subsequently measured, the LCD will display 10A. 3) To return to normal operation, press the zero key one more time. 4) Note that Relative mode is not available if the MIN/MAX mode is enabled. 5) Relative mode is not available in continuity or Hz mode. 6) Note that the Zero button is disabled if ohm and continuity or Hz functions are selected. 7) LCD displays relative numerical value without bargraph.

Data Hold To freeze a reading on the LCD, press the Data Hold key. The HOLD icon will appear and the measurement will be held on the meter’s LCD. To release the Data Hold function and return the meter to normal operation, press the Data Hold key again. Data Hold is disabled if ohm and continuity function are selected.

The Exteche EX845 provides TRMS AC/DC Current & Voltage measurements upto 1000A and 1000V respectively and has a built-in non-contact IR Thermometer with a laser pointer that is capable of measuring upto 270C. However the real benefit of the Extech EX845 is the Bluetooth transmitter with MeterLink technology that allows this clamp meter to wirelessly communicate with a wide range of Flir Thermal Imaging Cameras including the new E-Series. Valuable voltage and current readings can be wirelessly transmitted to a Flir infrared camera and be integrated with the thermal images to provide a comprehensive overview of an electrical system.

A Flir IR camera can quickly identify problems on electrical systems and provide infrared images which clearly locate the specific component with the fault. Using MeterLink the Extech EX845 allows a thermographer to quickly take an electrical readings on the faulty component and instantly record them on the thermal image they have just taken. In addition the EX845 clampmeter has a CAT IV 600V safety rating for added protection and making it suitable for industrial applications. The EX845 jaw opening size of 43mm will fit conductors up to 750MCM or two 500MCM. The TRMS feature ensures highly accurate readings of non-sinusoidal waveforms and the peak hold function can be used to capture inrush currents and Transients.
