To check the amount of ac ripple on the bus, switch the 7V's function switch to the vac function.
All the inputs on this industrial multimeter are updated to the third and CAT III, 1000 V. They are designed to withstand spikes in excess of 8 V. In the past, motor repair meant dealing with traditional three-phase motor failures that were largely the result of water, dust, grease, failed bearings, misaligned motor shafts, or just plain old age. Special shielding blocks high frequency, high-energy noise generated by large drive systems. The input voltage readings should be within 1% of one another when measured phase to phase with no load. Connect the red probe to one of the other two phase output voltage or motor terminals. Motor speed (Output frequency using voltage as a reference). *VDE Certification File: 943802-3940-0013 / 261572 / TL6 / KUJ.

If you can't access the DC bus, use the peak min max function on the multimeter to measure the dc bus voltage via the output voltage signal.
To ask our Fluke experts a question please include your contact details. Many of today's True RMS digital multimeters have bandwidths out to 20 kHz or more, causing them to respond not only to the fundamental component, which is what the motor really responds to, but to all of the high frequency components generated by the pwm drive. And they won't roll away, with two flat faces on the finger guard to hold everything still. A replacement kit that provides flexibility and comfort, and comes equipped with all SureGrip™ leads and probes. Press the yellow button to enable the low pass filter. Included with kit: Fluke i410 (1-400A AC RMS, 1-400A DC Current Clamp) and a Zippered vinyl carry case with moveable divider. For use with TL222 and TL224 test leads. A lot of time and money can be wasted replacing perfectly good parts when the problem is simply a loose connection. If the low pass filter isn't enabled, the output voltage readings may be 10 to 30% higher, as on a regular DMM (see Figure 1). A starter kit with both. Additionally, it is ideal for low voltage applications below 30 V AC and 60 V DC. Featuring a durable, zippered carrying case with padding and inside pocket, and high quality polyester exterior. Groups of pliers. That’s why you have a pack to carry it all. With the filter selected, the readings for both voltage and frequency (motor speed) should agree with the associated drive control display indications, if available. This will be the reference phase. Hang your meter in a variety of ways for convenient hands-free operation. Connect the black probe to one of the three phase output voltage or motor terminals. Dual-rated CAT IV 600V and CAT III 1000V. This is especially true when taking voltage, frequency and current measurements on the output side of the motor drive. Test Leads designed to improve steadiness with rubber overmolded surfaces and finger-hugging curves. Features hard stainless steel probe tips and one pair of slender probe bodies, which is ideal for probing closely spaced or recessed terminals. Fluke 87V Industrial Multimeter When productivity is on the line and you need to solve problems fast, the Fluke 87V delivers the accuracy and advanced troubleshooting capabilities you need. Regardless of clamp type, insure that all readings are within 10% of each other for proper balance. It also analyzes reviews to verify trustworthiness. Additionally, this stray voltage adapter test lead kit is compatible with all modern meters with standard input spacing. The low pass filter also allows for accurate current measurements when used with Hall-effect type clamps. Includes a unique function for accurately measuring noisy at the VFD and at the motor terminals. Identifies complex signal problems fast. Verify that the multimeter is reading a current of at least 20 amps (20mA in the display). We also accept wire transfers/EFT, cheques and purchase orders on approved credit. Designed to reliably measure the temperature of pipes ¼" (6 mm) to 1⅜" (35 mm) in diameter, at temperatures between -20 and 300°F (-29 and 149°C), while retaining a long service life.
Safe. Any good quality True RMS multimeter can verify proper input power to an ASD. Now, technicians won't have to guess whether the drive is operating correctly and delivering the correct voltage, current or frequency for a given control setting. Place the clamp around each of the output phase cables in succession, recording each of the readings as they're taken. But until now, there hasn't been a digital multimeter on the market able to accurately measure ASDs.
Features over molded surfaces and finger-hugging curves for a more comfortable and reliable grip, this test lead extension set is designed to improve steadiness in slippery hands.

Once the low pass filter is turned on, the meter will be in the 600 mV manual range mode. These insulated test leads provide the convenience and variety for test lead configurations by attaching clips, hooks and grabbers as needed. All of these measurements are especially helpful when taking measurements at the motor location when the drive's displays are not in view.
Place the clamp around each of the input supply phase cables in succession, recording each of the readings as they are taken. A high-frequency probe designed to convert a DC voltmeter with an input impedance of 10 MΩ into a high frequency (100 kHz to 500 Mhz) RF voltmeter. This measurement would not be possible without the low pass filter (see Figure 5). Leaving the black probe on the reference phase, now move the red probe to the third phase output voltage or motor terminal and record this reading. Likewise, choosing the right test tools for troubleshooting the drive, the motor, and the connections is of utmost importance. When using a DMM for measurements on these high energy systems, make sure it's rated at a minimum for CAT III 600V and preferably for CAT IV 600V/CAT III 1000V. Adjustable collar provides two ranges of jaw openings up to 1.81" (30 mm). Additionally, it's probe's DC output is calibrated to equal the RMS value of sine wave input. Features a tapered tip, making this tapered temperature probe ideal for use in air, non-caustic gas, and surface applications. Technicians use many different methods to troubleshoot an electrical circuit, and a good troubleshooter will always find the problem - eventually. To measure the ac voltage supply to the input side of the drive at the drive: Measuring the input current generally requires a current clamp accessory.
