Clamp Multimeter for Current, Voltage, Power, Harmonics and Frequency, 1000 V CAT IV
Thanks to its large clamp opening, the METRAclip 88 clamp multimeter is suitable for the low-voltage range with high power values, e.g. in the chemicals and petrochemicals industry, as well as for mixed AC+DC measurements at distribution and transmission networks.
Features in Detail:
Display Memory
(data hold) The momentary measured value can be “frozen” at the display.
True Inrush
Measurement of motor starting current characteristics based on the relationship between amplitude and time. This function makes it possible to track rapid current changes of the damped sinusoidal oscillation type by measuring successive TRMS values which are calculated over ½, 1, 2½, 5, and 10 periods based upon the largest calculated TRMS value and are refreshed via a half-wave.
Relative and Differential Measurements
A momentary measured value can be saved as a reference value. A differential value based on the momentary measured value and the reference value can be generated and displayed for each following measurement. Alternatively, the differential value can be related to the reference value and displayed as a relative value as a percentage for each following measurement.
Safety Devices
Visual indication is provided in the event that the measuring range is exceeded.
An intermittent acoustic signal warns the user of voltages that are equal to or larger than the safety voltage of 1000 VDC or TRMS.
Automatic Shutdown
The device is shut down automatically in the event that none of the keys or the rotary switch are activated for a duration of 10 minutes. The automatic shutdown can be deactivated.
Measured Value Recording and Data Transmission via Bluetooth to the PC
The recording function can be used to continuously save measurement results to the device at a specified interval. As a standard feature, a recording interval of 60 seconds is preset on the device. This value can be set to anywhere between 1 and 600 seconds (10 minutes) in the configuration mode.
Evaluation with a PC Program
With a connection between the clamp and the PC, the measurement data to be transmitted to the evaluation program at the PC can be selected by the user. The measurement data can then be displayed as a graphic or exported to an Excel table.
