Relative Mode
In Relative Mode, the Meter will zero the display and store the present reading as the
reference for subsequent measurements. The Meter is locked into the selected manual range
when you pushed
R.
The reading shown is always the difference between the present reading and the stored
reference value. For example, if the stored reference value is 15.00 V and the live reading is
14.10 V, the display shows -0.90 V (delta).
The measurements show on the display in this order:
Delta
Reference
Live
Push
R again to exit the Relative Mode.
Display Hold
XW Warning
To prevent possible electrical shock, fire, or personal injury, do not use the
HOLD function to measure unknown potentials. When HOLD is turned on, the
display does not change when a different potential is measured.
In the Display Hold Mode, the Product captures the live reading on the display and does not
update until you exit the Display Hold Mode. To hold a measurement on the display, push
M.
The display shows h when Display Hold is turned on.
Push
M again to exit Display Hold Mode and show live measurements on the display.
Auto Hold Mode
The Auto Hold Mode captures the present reading on the display. When a new, stable reading
is detected, the Meter beeps and displays the new reading. To enter or exit the Auto Hold
Mode, push
M >2 s.
For V ac, V dc, VA, A ac, A dc, and resistance functions, the threshold is 1% of range and the
fluctuation is 0.2 % of range.

Limit Gauge
For high-volume and repetitive measurements of V ac, V dc, mV ac, mV dc, A dc, and A ac ,
you can use the Limit Gauge to monitor the measurements. After setup, a visual gauge shows
on the display with the set range and where the present measurement is in that range. Any
measurement outside a set percentage or range causes an audible and visible alarm.
Note
The measurement range is set to auto range when in the limit gauge function.
As an example, in the V ac mode, set the limit gauge by digit to the range of 180 V to 250 V
and apply an input signal of 220 V/50 Hz. See Figure 1.
Figure 1. Limit Gauge
The Limit Gauge has setup options:
Option 1. set the expected value and acceptable deviation percentage. For example, 1000 V
and a ±10 % has an acceptable range of 900 V to 1100 V. Any measurement above or below
the set value causes an audible and visible alarm.
Option 2. Set a manual range. For example, set 900 V to 1100 V as acceptable range. Any
measurement above or below the range causes an audible and visible alarm.
Option 3. Select a previous setup. Use this option for often-used setups or recurring site
inspections.

Inputs
Table 4 is a list of the input functions.
AC Low Value Input Behavior of True-RMS Meters
Average responding meters can accurately measure only pure sinewaves. The 283 FC
True-RMS Meter can accurately measure distorted waveform signals. A minimum input
voltage is necessary for True-RMS converters to make a measurement. Because of this
minimum input, True-RMS meter specifications are only good for 1 % to 100 % of range. Non-
zero digits that are shown on a True-RMS meter when the test leads are open or are shorted
are possible. This has no effect on the ac measurement accuracy of signals that are more than
1% of range.
Unspecified input levels on the lowest ranges are:
AC voltage less than 1 % of each V ac or mV ac range.
AC current less than 1 % of 60 A ac or 0.6 A ac.
Wireless Radio Setup
The Product uses wireless radio technology to send or receive measurements to the a283 FC
Current Clamp or the Fluke Connect® app. The maximum distance between meter and clamp
for operation is 10 m (33 ft).

AC or DC Current with a283 FC Current Clamp
See Pair with a283 FC Current Clamp for more information about how to measure dc or ac
amps with the
C
B
function.
AC VA and DC Power
The ac VA or dc power measurement is a calculation between a voltage (using test leads
connected to the Meter) and an amperage input (from the Clamp):
Apparent Power (VA) = Voltage (V) × Current (A)
This calculated value shows on the display to save manual calculation and recording time.
You can use the Fluke Connect feature to share the calculation on your mobile device.
Note
The Meter only calculates apparent power (S, measured in VA) and not reactive power
(Q, measured in VAR) or True power (P, measured in Watts). For dc power there is no
difference in Watts and VA. For ac power the readout shows AC VA.
To measure dc power or ac VA:
1. Turn control knob to
E or 4.
2. Push
N to go to the A mode.
3. Make sure the Clamp is clear of any current carrying conductors.
4. On the Clamp, push
F to compensate (zero) for outside influences for dc power.
5. Position the Clamp jaw around the conductor.
6. Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
7. Touch the probes to the test points of the circuit.
The display shows the measurement of VA and current.
The display also shows
B to indicate that the measurement is from the Clamp jaw.
Note
Push
N to toggle the readout between VA and voltage.

Resistance Measurements
XW Warning
To prevent possible electrical shock, fire, or personal injury, disconnect power
and discharge all high-voltage capacitors before you measure resistance,
continuity, or capacitance.
The Product sends a small current through the circuit for resistance measurements. Because
the current flows through all possible paths between the probes, the resistance measured is
the total resistance of all paths between the probes.
The resistance ranges are 600.0 Ω, 6.000 kΩ, 60.00 kΩ, 600.0 kΩ, 6.000 MΩ, and 50.00 MΩ. Set
the Product as shown in Figure 3 to measure resistance.
