True-rms Multimeter
Introduction
The Fluke Model 116C, is a battery-powered, true-rms
multimeter (hereafter "the Meter") with a 6000-count
display and a bar graph.
This meter meets CAT III IEC 61010-1 2nd Edition
standards. The IEC 61010-1 2nd Edition safety standard
defines four measurement categories (CAT Ito 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 Ysymbol is displayed when
the Meter measures a voltage ≥30 V or a voltage
overload (OL) condition. When making frequency
measurements >1 kHz, the Ysymbol is unspecified.

Safety Information
A "XWWarning" statement identifies hazardous conditions and actions that could cause bodily harm or death.
A "WCaution" statement identifies conditions and actions that could damage the Meter or the equipment under test.
To avoid possible electric shock or personal injury, follow these guidelines:
•Use the Meter only as specified in this manual or the protection provided by the Meter might
be impaired.
•Do not use the Meter or test leads if they appear damaged, or if the Meter is not operating
properly.
•Always use proper terminals, switch position, and range for measurements.
•Verify the Meter's operation by measuring a known voltage. If in doubt, have the Meter
serviced.
•Do not apply more than the rated voltage, as marked on Meter, between terminals or
between any terminal and earth ground.
•Use caution with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc. These voltages pose
a shock hazard.
•Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
•Do not use the Meter around explosive gas or vapor.
•When using test leads or probes, keep your fingers behind the finger guards.
•Only use test leads that have the same voltage, category, and amperage ratings as the meter
and that have been approved by a safety agency.
•Remove test leads from Meter before opening the battery door or Meter case.

•Comply with local and national safety requirements when working in hazardous locations.
•Use proper protective equipment, as required by local or national authorities when working
in hazardous areas.
•Avoid working alone.
•Use only the replacement fuse specified or the protection may be impaired.
•Check the test leads for continuity before use. Do not use if the readings are high or noisy.
•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).

Battery Saver ("Sleep Mode")
The Meter automatically enters "Sleep mode" and blanks
the display if there is no function change, range change or
button press for 20 minutes. Pressing any button or
turning the rotary switch awakens the Meter. To disable the
Sleep mode, hold down the gbutton while turning the
Meter on. The Sleep mode is always disabled in the MIN
MAX AVG mode.
MIN MAX AVG Recording Mode
The MIN MAX AVG recording mode captures the minimum
and maximum input values (ignoring overloads), and
calculates a running average of all readings. When a new
high or low is detected, the Meter beeps.
•Put the Meter in the desired measurement function and
range.
•Press pto enter MIN MAX AVG mode.
•Mand MAX are displayed and the highest
reading detected since entering MIN MAX AVG is
displayed.
•Press pto step through the low (MIN), average
(AVG), and present readings.
•To pause MIN MAX AVG recording without erasing
stored values, press f. Kis displayed.
•To resume MIN MAX AVG recording, press fagain.
•To exit and erase stored readings, press pfor at
least one second or turn the rotary switch.
Display HOLD
XWWarning
To avoid electric shock, when Display
HOLD is activated, be aware that the
display will not change when you
apply a different voltage.
In the Display HOLD mode, the Meter freezes the display.
1. Press fto activate Display HOLD. (Kis
displayed.)
2. To exit and return to normal operation, press for
turn the rotary switch.
Backlight
Press Qto toggle the backlight on and off. The backlight
automatically turns off after 40 seconds. To disable
backlight auto-off, hold down Qwhile turning the Meter
on.
Manual and Autoranging
The Meter has both Manual and Autorange modes.
•In the Autorange mode, the Meter selects the range with
the best resolution.
•In the Manual Range mode, you override Autorange and
select the range yourself.
