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.

To set up:

1. Select the measurement function and range.
2. Push enter MIN MAX AVG mode.
3. MAX show on the display. The highest reading detected since entering MIN MAX AVG shows on the display.
4. Push to step through the low (MIN), average (AVG), and present readings.
5. To pause MIN MAX AVG recording without erasing stored values, push . ( shows on the display.)
6. To resume MIN MAX AVG recording, push again.
7. To exit and erase stored readings, push for at least one second, or turn the rotary switch.

Display HOLD

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 to activate Display HOLD. ( shows on the display.)
2. To exit and return to normal operation, push or turn the rotary switch.

Backlight

Push to 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 for 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 for 1 second to enter Manual range. (Manual shows on the display.) Push to 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 while 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 ble 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.

Table 5. Power-Up Options

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.

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 x 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

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

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.

Measuring Capacitance

Measuring Temperature

Warning
To prevent risk of electric shock, do NOT connect 80BK to live circuits.

Measuring Frequency

Warning
To prevent 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.

Making Low Impedance Capacitance Measurements

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

Measuring Current above 600 μA

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, AC or DC, selected for your current probe. Refer to a Fluke catalog or contact your local Fluke representative for compatible current clamps.

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 replacement and case cleaning.

Replacing the Battery

Warning
To prevent shock, injury, or damage to the Meter, remove test leads from the Meter before opening the case or battery door.
See Figure 1 for disassembly.

Figure 1. Disassembly

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.

Cleaning

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