Fluke 115 True-RMS Field Technician Digital Multimeter

115 compact field-technician multimeter explained

The Fluke 115 True-RMS Digital Multimeter (115) is a compact true-RMS digital multimeter for field service. It measures AC and DC voltage up to 600 V and current up to 10 A, with resistance, continuity, frequency and capacitance, in a body designed for one-handed use. Seven Star LLC supplies 115 in Oman and the GCC as an independent supplier in Muscat, not affiliated with the manufacturer.

The 110 series uses plain model numbers, so the table explains the identifiers and the figures that matter on a work order.

115 technical specifications

Data are from the manufacturer product page and the detailed specification sheet for the 114/115/116/117 family.

How the Fluke 115 True-RMS Digital Multimeter works

The 115 measures with one-handed operation in mind: a rotary switch selects the function, the display shows a six-thousand-count value, and a bar graph supports trend watching. True-RMS conversion lets it read distorted waveforms from drives and electronic loads correctly within the stated frequency range.

Min/Max/Average with elapsed time records fluctuations over a period, which is useful for supply dips and intermittent contacts. The holster has probe holders, so leads can be parked without loose ends in a toolbag.

Key features

• Min/Max/Average with elapsed time
• Backlit 6000-count display
• Frequency and capacitance functions
• Holster with probe holders
• Three-year warranty

Where 115 fits and related Fluke models

The 115 sits between the 114 (go/no-go with AutoVolt and LoZ) and the 117 (adds non-contact voltage detection and AutoVolt). The 116 is the HVAC-oriented variant with temperature and microamp functions. The 115 is the one for general field service when you do not need those extras.

For 1000 V environments, the 170 series (175, 177, 179) is the step up in rating.

Selection checklist for 115

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

• Voltage rating: CAT III 600 V; for 1000 V work choose a 170 series model.
• No temperature function; choose the 116 for HVAC temperature and microamps.
• Current direct up to 10 A.
• Leads and case: the pack includes a holster and PVC leads.

Safe use, care and maintenance of 115

• 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 115 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 115 True-RMS Digital 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 115 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.

The 115 suits maintenance technicians on building services, small motors, lighting and control panels across industrial estates, utilities and facility management in Oman. Its compact size makes it easy to carry on an inspection round in hot, dusty plant areas.

115 compared with nearby models

The 113 uses a separate datasheet; the 114, 115 and 116 share a detailed specification sheet.

Information to send with an RFQ for 115

To prepare an accurate quotation, please send:

• Exact model 115 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 115

Store the Fluke 115 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 115, 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.
