Fluke 87 v true-rms multimeter with temperature
Here is what Fluke has to say:
* True-rms ac voltage and current for accurate measurements on non linear signals
* Selectable filter for accurate voltage and frequency measurements on motor drives
* 4-1/2 digit mode for precise measurements
* Built-in thermometer lets you carry one less tool
* Large display digits and two-level bright white backlight for increased visibility
* 10,000 F capacitance range for components and motor caps
* Min/Max and average recording to capture variations automatically
* Relative mode to remove test lead resistance from low ohms measurements
* Improved sleep mode for long battery life
* Access door for fast battery changes without breaking the calibration seal
* Removable holster with built in test lead and probe storage
* Cat IV 600 V and Cat III 1000 V electrical safety ratings
* Correctly measure pulse-width modulated motor drive signals
Until now, there hasn't been a multimeter able to accurately measure adjustable speed drives. But the Fluke 87V is designed specifically to handle these complex signals. Think of the potential productivity you'll gain by taking the guesswork out of drive system troubleshooting. Measurements are correct each and every time.
* Unique function for accurate measurements of noisy pulse-width modulated AC voltage.
* Measures correctly at the ASD and at the motor terminals
* Accurately measure the frequency (motor speed). Frequency measurement not affected by the ASDs carrier frequency
* Measure AC current with an optional current clamp accessory
* Compare reading from the 87V with the display on the ASD
* Special shielding blocks high frequency, high-energy noise generated by large drive systems
Complex PWM drive signals are not a problem for the Fluke 87V
