Introduction

The Fluke Model 110, Model 113, Model 114, Model 115, and Model 117 (the Meter or Product) are batterypowered, true-rms multimeters with a 6000-count display and a bar graph. This manual applies to all models. All figures show the Model 117 unless indicated.

Safety Information

For Product safety information, see the printed 110/113/114/115/117
Safety Information included with the Product or located on the Fluke website.

Unsafe Voltage

To alert you to the presence of a potentially hazardous voltage, the Z symbol is displayed when the Meter measures a voltage ≥30 V or a voltage overload (OL) condition. When making frequency measurements >1 kHz, the Z 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, LEAd is briefly displayed and an audible beep sounds when you move the rotary switch to or from any A (Amps) position.

Making Basic Measurements

When connecting the test leads to the circuit or device, connect the common (COM) test lead before connecting the live lead; when removing the test leads, remove the live lead before removing the common test lead.

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

Measuring Resistance

Testing for Continuity

Note
Use the continuity function as a fast, convenient method to check for opens and shorts. For maximum accuracy in making resistance measurements, use the Meter's resistance () function.

Measuring AC and DC Voltage

Using Auto Volts Selection (114, 117)

With the function switch in the position, the Meter automatically selects a dc or ac voltage measurement based on the input applied between the V or + and COM jacks.
This function also sets the Meter's input impedance to approximately 3 kΩ to reduce the possibility of false readings due to ghost voltages.

Measuring AC and DC Millivolts (110, 114, 115, 117)

With the function switch in the position, the Meter measures ac plus dc millivolts. Press to set the Meter to dc millivolts.

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 open-circuit potential to earth is >600 V.
• Check the Meter's fuse before testing. See Testing the Fuse (115, 117).
• 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.

To measure current:

1. Turn circuit power off.
2. Break the circuit
3. Insert the Meter in series with the circuit, and then turn circuit power on.

Measuring Current above 10 Amps (110, 114, 115, 117)

The millivolt and voltage function of the Meter can be used with an optional mV/A output Current Probe to measure currents that exceed the rating of the Meter. Make sure the Meter has the correct function selected, AC or DC, for your current probe. Refer to a Fluke catalog or contact your local Fluke representative for compatible current clamps.

Measuring Capacitance (113, 115, 117)

Measuring Frequency (115, 117)

To avoid electrical shock, disregard the bar graph for frequencies >1 kHz. If the frequency of the measured signal is >1 kHz, the bar graph and are unspecified.

The Meter measures the frequency of a signal by counting the number of times the signal crosses a trigger level each second. The trigger level is 0 V, 0 A for all ranges.

Press to turn on or turn off the frequency measurement function on and off. Frequency works with ac functions only.

In frequency, the bar graph and range annunciator indicate the ac voltage or current present.

Select progressively lower ranges using manual ranging for a stable reading.

Detecting AC Voltage Presence (117)

To detect the presence of ac voltage, place the top of the Meter close to a conductor. The Meter gives an audible as well as visual indication when voltage is detected. The sensitivity settings are:

• : use on flush mounted wall sockets, power strips, flush mounted industrial outlets and various power cords.
• : for ac voltage detection on other styles of recessed power connectors or sockets where the actual ac voltage is recessed within the connector itself.

The VoltAlert detector works in bare wire applications with voltages as low as 24 V in the Hi setting.

If there is no indication, voltage could still be present. Do not rely on the VoltAlert detector with shielded wire. Operation may be effected by differences in socket design, insulation thickness and type.

Making Low Impedance Capacitance Measurements (115, 117)

For making capacitance measurements on cables with ghost voltage:

1. Hold as you turn on the Meter to enable the low-input impedance Capacitance mode.
2. Wait until shows on the display.

In this mode, capacitance measurements will have a lower accuracy and lower dynamic range.

Note
This setting is not saved when the Meter is turned off or goes into sleep mode.

Testing Diodes (113, 115, 117)

Using the Bargraph

The bar graph is like the needle on an analog meter. It has an overload indicator ( ) to the right and a polarity indicator () to the left.

Because the bar graph is much faster than the digital display, the bar graph is useful for making peak and null adjustments.

The bar graph is disabled when measuring capacitance. In frequency, the bar graph and range annunciator indicates the underlying voltage or current up to 1 kHz.

The number of segments indicates the measured value and is relative to the full-scale value of the selected range.

In the 60 V range, for example (see below), the major divisions on the scale represent 0, 15, 30, 45, and 60 V. An input of -30 V turns on the negative sign and the segments up to the middle of the scale.

Maintenance

Maintenance of the Meter consists of battery and fuse replacement, as well as case cleaning.

Testing the Fuse (115, 117)

Test fuse as shown in Figure 1.

Replacing the Battery and Fuse

To avoid shock, injury, or damage to the Meter:

• Remove test leads from the Meter before opening the case or battery door.
• Use ONLY a fuse with the amperage, interrupt voltage, and speed ratings specified.

To remove the battery door for battery replacement:

1. Remove the test leads from the Meter.
2. Remove the battery door screw.
3. Use the finger recess to lift the door slightly.
4. Lift the door straight up to separate it from the case.
5. The battery fits inside the battery door, which is then inserted into the case, bottom edge first, until it is fully seated. Do not attempt to install the battery directly into the case.
6. Install and tighten battery door screw.

To open the case for fuse replacement:

1. Remove the test leads from the Meter.
2. Remove the Meter from its holster.
3. Remove two screws from the case bottom.
4. Separate the case bottom from the case top.
5. Remove the fuse from its holder and replace it with an 11 A, 1000 V, FAST fuse having a minimum interrupt rating of 17,000 A. Use only Fluke PN 803293.
6. To re-assemble the Meter, first attach the case bottom to the case top, then install the two screws. Finally, insert the Meter into its holster.

Cleaning

Wipe the case with a damp cloth and mild detergent. Dirt or moisture in the terminals can affect readings.
