Fluke 287 True-RMS Electronics Logging Multimeter

287 logging multimeter with TrendCapture explained

The Fluke 287 True-RMS Electronics Logging Multimeter (287) is a high-resolution true-RMS multimeter with on-board logging and a graphical TrendCapture display. A 50,000-count screen, 0.025% basic DC accuracy and a 100 kHz AC bandwidth make it a handheld alternative to a bench meter. Seven Star LLC supplies 287 in Oman and the GCC as an independent supplier in Muscat, not affiliated with the manufacturer.

The 287 is the electronics-oriented member of the 280 series. The table decodes its main identifiers.

287 technical specifications

Data from the manufacturer product page and datasheet for the Fluke 287. Wireless use needs the optional ir3000 FC connector.

How the Fluke 287 True-RMS Electronics Logging Multimeter works

The 287 samples at high resolution and stores readings internally. TrendCapture plots them on the 1/4 VGA screen so that an intermittent fault or a slow drift can be seen immediately, and zoom lets the user magnify the trend up to 14 times without downloading to a PC.

A selectable AC filter smooths noisy readings, adjustable thresholds decide when a new event starts, and a real-time clock time-stamps saved measurements. Named saved measurements can be recalled later in the field.

Key features

• 50,000-count 1/4 VGA display
• Zoom on trend, up to 14 times
• Up to 10,000 logged readings
• Real-time clock time stamps
• 100 mF capacitance range

Where 287 fits and related Fluke models

The 287 sits between the 28 II rugged meter and the 289 industrial logging meter in capability. The 289 adds industrial features such as a low-pass filter for drives; the 287 is aimed at electronics and design validation.

For simple go/no-go field use, the 17x series is lighter and cheaper.

Selection checklist for 287

Confirm the following points before ordering, so that the instrument matches the work and the safety rules of your site.

• Logging needs and the number of readings per session.
• Resolution and accuracy needs that justify 50,000 counts.
• Battery type: six AA cells.
• Wireless connection requires an optional adapter.

Safe use, care and maintenance of 287

• Before each shift, inspect the case, the holster and the test leads. Cracked insulation, exposed metal or a loose input jack means the leads should be replaced before the 287 touches any live circuit.
• Confirm the meter on a known live source before and after a measurement that decides whether a circuit is dead. Never rely on a single reading when the result will be used to release a lock-out.
• Keep the input fuses to the specified type only. A blown fuse in the current inputs is the most common service event on a multimeter used on motor circuits, and a wrong fuse defeats the safety design of the Fluke 287 True-RMS Electronics Logging Multimeter.
• Replace the battery when the low-battery symbol appears, because readings near the lower end of the range become unreliable on a weak cell. Remove the battery before long storage.
• Store the instrument clean and dry. In coastal Oman, wipe off salt film and condensation after outdoor use and avoid leaving it in a vehicle cabin in summer.

Typical applications of 287 in Oman and the GCC

Handheld multimeters are carried in every plant. In Oman, oil and gas facilities, power stations, desalination plants and petrochemical sites rely on them for control-panel faults, motor circuits, instrument loops and routine electrical checks.

In Oman the 287 is used in instrumentation workshops, calibration labs and commissioning teams verifying control loops, power supplies and sensors. Logging helps document transients and slow drifts at plants where permanent monitoring is not available.

Information to send with an RFQ for 287

To prepare an accurate quotation, please send:

• Exact model 287 and the quantity required.
• Whether the meter is for a lab, a workshop or field service, so the correct accessory set can be quoted.
• Required test lead type and any extra clips or probes.
• Temperature probe, case or magnetic hanger requirements.
• Whether calibration traceability paperwork is needed on delivery.
• Delivery point in Oman or elsewhere in the GCC and the required date.

Storage, handling and spares for the Fluke 287

Store the Fluke 287 in its case or holster with the test leads disconnected. Remove the batteries if the meter will not be used for several weeks, because leaking cells can damage the battery contacts. In Oman and the GCC, do not leave the instrument in a parked vehicle during summer, where cabin temperature can go well above the storage limit in the user manual.

• Inspect test leads, probes and clamps before each use and replace any lead with damaged insulation or exposed metal.
• Use only leads and accessories rated for the same or a higher measurement category than the work you do.
• Keep spare fuses of the exact type given in the manual; a wrong fuse removes the protection the meter is built with.
• Plan a regular calibration interval, often twelve months, and keep the certificate with the instrument records.

If your team uses several units of the Fluke 287, it is useful to order spare test leads and batteries in the same RFQ, so that a meter is not taken out of service for a simple accessory.
