True-rms Multimeters

Introduction

The Fluke Model 114, Model 115, and Model 117 are battery-powered, true-rms multimeters (hereafter "the Meter") with a 6000-count display and a bar graph. This manual applies to all three models. All figures show the Model 117.

These meters meet CAT III IEC 61010-1 2 standards. The IEC 61010-1 2nd 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, audible beep sounds when you move the rotary switch to

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.

True-rms Multimeters Safety Information

• 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)(114 and 117 only).

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 g 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 p to enter MIN MAX AVG mode.

• Mand MAX are displayed and the highest

reading detected since entering MIN MAX AVG is displayed.

• Press p to step through the low (MIN), average

(AVG), and present readings.

• To pause MIN MAX AVG recording without erasing

stored values, press

• To resume MIN MAX AVG recording, press fagain.

• To exit and erase stored readings, press

When you turn the Meter on, it defaults to Autorange and Auto is displayed.

1. To enter the Manual Range mode, press Manual is displayed.

2. In the Manual Range mode, press the range. After the highest range, the Meter wraps to the lowest range.

You cannot manually change the range in the MIN MAX AVG or Display HOLD modes.

If you press qwhile in MIN MAX AVG or Display Hold an invalid operation and the range does not change.

3. To exit Manual Range, press or turn the rotary switch. The Meter returns to Autorange and Auto is displayed.

Measuring Resistance

To avoid electric shock, injury, or damage to the Meter, disconnect circuit power and discharge all highvoltage capacitors before testing resistance, continuity, diodes, or capacitance.

XWWarning

Testing for Continuity

The continuity function works best as a fast, convenient method to check for opens and shorts. For maximum accuracy in making resistance measurements, use the Meter’s resistance (e) function.

Measuring AC or DC Current (115 & 117)

To avoid personal injury or damage to the Meter:

• Never attempt to make an in-circuit

current measurement when the opencircuit potential to earth is

>600 V.

• Check the Meter's fuse before testing.

(See “Testing the Fuse”)

• Use the proper terminals, switch

position, and range for your measurement.

• Never place the probes in parallel with a

circuit or component when the leads are plugged into the A (Amps) terminals.
