Safety Information
General Safety Information is in the printed Safety Information document that ships with the
Product and at www.fluke.com. More specific safety information is listed where applicable.
A Warning identifies hazardous conditions and procedures that are dangerous to the user. A
Caution identifies conditions and procedures that can cause damage to the Product or the
equipment under test.
Unsafe Voltage
To alert you to the presence of a potentially hazardous voltage, the Zsymbol shows when the
Meter measures a voltage ≥30 V or a voltage overload (OL) condition. When making frequency
measurements >1 kHz, the Zsymbol is unspecified.

Rotary Switch Positions
Table 4 is a list of the rotary switch positions and features.
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
5
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.
To s e t u p :
1. Select the measurement function and range.
2. Push pto enter MIN MAX AVG mode.
3. Mand MAX show on the display. The highest reading detected since entering MIN
MAX AVG shows on the display.
4. Push pto step through the low (MIN), average (AVG), and present readings.
5. To pause MIN MAX AVG recording without erasing stored values, push f. (Kshows
on the display.)
6. To resume MIN MAX AVG recording, push f again.
7. 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 Ta b l e 5 while 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 prevent 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
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
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
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.
• Use the proper terminals, switch position, and range for your measurement.
To measure flame rectification circuits:
1. Turn the function switch to $.
2. Connect the Meter between the flame sensor probe and the control module.
3. Turn heating unit on and record μA measurement.
