True-rms Multimeters
Introduction
The Fluke Model 115C, and Model 117C are battery-
powered, true-rms multimeters (hereafter "the Meter")
with a 6000-count display and a bar graph. This manual
applies to both models. All figures show the Model
117C.
These meters meet CAT III IEC 61010-1 2
nd
Edition
standards. The IEC 61010-1 2
nd
Edition safety standard
defines four measurement categories (CAT I to IV)
based on the magnitude of danger from transient
impulses. CAT III meters are designed to protect
against transients in fixed-equipment installations at the
distribution level.

Unsafe Voltage
To alert you to the presence of a potentially
hazardous voltage, the Y symbol is displayed when
the Meter measures a voltage ≥ 30 V or a voltage
overload (OL) condition. When making frequency
measurements >1 kHz, the Y symbol is unspecified.
Test Lead Alert

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,
