True-rms Multimeters
Introduction
The Fluke 110 PLUS and 115 are battery-powered, true-
rms multimeters (hereafter "the Meter" or the “Product”) with
a 6000-count display and a bar graph. This manual applies
to all models. All figures show the 115.

Unsafe Voltage
The hazardous voltage warning ( Y) shows on the display
when the Meter detects a voltage ≥30 V or a voltage
overload (OL) condition. When making frequency
measurements >1 kHz, the Ysymbol is unspecified.
Test Lead Alert
XW Warning
Personal injury or damage to the Meter can
occur if you attempt to make a measurement
with a lead in an incorrect terminal.
To remind you to check that the test leads are in the
correct terminals, is briefly displayed and an audible
beep sounds when you move the rotary switch to or
from any A(Amps) position.

Safety Information
A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that can
cause damage to the Product or the equipment under test.
XW Warning
To prevent possible electrical shock, fire, or personal injury:
•Read all safety information before you use the Product.
•Carefully read all instructions.
•Do not use the Product around explosive gas, vapor, or in damp or wet environments.
•Comply with local and national safety codes. Use personal protective equipment (approved rubber gloves,
face protection, and flame-resistant clothes) to prevent shock and arc blast injury where hazardous live
conductors are exposed.
•Examine the case before you use the Product. Look for cracks or missing plastic. Carefully look at the
insulation around the terminals.
•Do not use test leads if they are damaged. Examine the test leads for damaged insulation and measure a
known voltage.
•Limit operation to the specified measurement category, voltage, or amperage ratings.
•Use the correct terminals, function, and range for measurements.
•Do not touch voltages > 30 V ac rms, 42 V ac peak, or 60 V dc.
•Do not exceed the Measurement Category (CAT) rating of the lowest rated individual component of a
Product, probe, or accessory.
•Use Product-approved measurement category (CAT), voltage, and amperage rated accessories (probes,
test leads, and adapters) for all measurements.

•Do not apply more than the rated voltage, between the terminals or between each terminal and earth
ground.
•Remove all probes, test leads, and accessories that are not necessary for the measurement.
•Do not use in CAT III or CAT IV environments without the protective cap installed on test probe. The
protective cap decreases the exposed probe metal to <4 mm. This decreases the possibility of arc flash
from short circuits.
•Do not work alone.
•Measure a known voltage first to make sure that the Product operates correctly.
•Replace the batteries when the low battery indicator shows to prevent incorrect measurements.
•Remove the batteries if the Product is not used for an extended period of time, or if stored in temperatures
above 50 °C. If the batteries are not removed, battery leakage can damage the Product.
•Remove all probes, test leads, and accessories before the battery door is opened.
•The battery door must be closed and locked before you operate the Product.
•Do not use the Product if it operates incorrectly.
•Disable the Product if it is damaged.
•Use the Product only as specified, or the protection supplied by the Product can be compromised.
WCaution
Do not use the Auto Volts function to measure voltages in circuits that could be damaged by this function’s low
input impedance (≈3 kΩ) (110 PLUS only).
