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 Zsymbol is displayed when the Meter

measures a voltage ≥30 V or a voltage overload (OL) condition. When making frequency measurements >1 kHz,

the Zsymbol 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, LEAd is briefly displayed and an audible

beep sounds when you move the rotary switch to or from any A(Amps) position.

Error Messages

Table 4is a list of error messages for the Meter.

Battery Saver™ (Sleep Mode)

If the Meter is ON, but inactive and not connected to voltage for more than 20 minutes, the display goes blank to

save battery life.To use the Meter, press any button or turn the rotary switch. To disable the Sleep mode, see

Power-Up Options. 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 the Meter detects a new high or low, the Meter beeps.

Note

Autoranging and Battery Saver™ are disabled in MIN MAX AVG mode.

1. Select the measurement function and range.

2. Push pto enter MIN MAX AVG mode.

Mand MAX show on the display. The highest reading detected since entering MIN MAX AVG shows

on the display.

3. Push pto step through the low (MIN), average (AVG), and present readings.

4. To pause MIN MAX AVG recording without erasing stored values, push f. (Kshows on the display.)

5. To resume MIN MAX AVG recording, push f again.

6. To exit and erase stored readings, push pfor at least one second, or turn the rotary switch.

Display HOLD

XW Warning

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. Push fto activate Display HOLD. (Kshows on the display.)

2. To exit and return to normal operation, push for turn the rotary switch.

Backlight

Push Qto toggle the backlight on and off.

The backlight automatically turns off after 40 seconds. To disable backlight auto-off, see Power-Up Options.

Manual and Autoranging

The Meter has both Manual and Autorange modes. The Meter defaults to Autorange. To toggle between Manual

and Autorange, push qfor 1 second.

• 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. Push qfor 1 second to

enter Manual range. (Manual shows on the display.) Push qto increment the range. After the highest

range, the Meter wraps to the lowest range.

Note

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

qwhile in MIN MAX AVG or Display Hold, the Meter beeps twice, indicating an invalid operation and

the range does not change.

Power-Up Options

To select a Power-Up Option, hold down the button indicated in Table 5while turning the Meter from OFF to any

other function. Power-Up Options are canceled when you turn off the Meter and when sleep mode is activated.

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.

XW Warning

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 (e)function.

Measuring AC and DC Voltage

Using Auto Volts Selection (114, 117)

With the function switch in the xposition, 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 kΩto 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 lposition, the Meter measures ac plus dc millivolts. Press gto set the

Meter to dc millivolts.

Measuring AC or DC Current (115, 117)

XW Warning

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.
