753/754 Users Manual Damping Measurements The Product normally applies a software filter to dampen measurements in all functions except continuity. The specifications assume that damping is turned on. The damping method is a running average of the last eight measurements. Fluke recommends leaving damping on. Turning damping off may be useful when measurement response is more important than accuracy or noise reduction. To turn damping off, push the More Choices softkey twice, then push the Dampen softkey so that Off is shown. Push Dampen again to turn damping back on. The default state is On. Note If a measurement falls outside a random noise window, a new average is started. If damping is turned off, or until measurements are fully damped, the  symbol is displayed. Source Mode The operating mode (for example, MEASURE, SOURCE) is shown on the display. If the Product is not in SOURCE mode, push  until SOURCE is shown. The Product must be in SOURCE mode to change any of the SOURCE parameters. Source Electrical Parameters To select an electrical source function: 1. Connect the test leads as shown in Figure 18, depending on the source function. 2. Push  for current,  for dc voltage, h for frequency, or q for resistance. 3. Record the necessary output value, then push . For example, to source 5.5 V dc, push  5 .  . 44

Damping Measurements
The Product normally applies a software filter to dampen
measurements in all functions except continuity. The
specifications assume that damping is turned on. The
damping method is a running average of the last eight
measurements. Fluke recommends leaving damping on.
Turning damping off may be useful when measurement
response is more important than accuracy or noise
reduction. To turn damping off, push the
More Choices
softkey twice, then push the
Dampen
softkey so that
Off
is
shown. Push
Dampen
again to turn damping back on. The
default state is
On
.
Note
If a measurement falls outside a random noise window,
a new average is started. If damping is turned off, or
until measurements are fully damped, the
symbol is
displayed.
Source Mode
The operating mode (for example, MEASURE, SOURCE) is
shown on the display. If the Product is not in SOURCE
mode, push
until SOURCE is shown. The Product
must be in SOURCE mode to change any of the SOURCE
parameters.
Source Electrical Parameters
To select an electrical source function:
1.
Connect the test leads as shown in Figure 18,
depending on the source function.
2.
Push
for current,
for dc voltage,
h
for
frequency, or
q
for resistance.
3.
Record the necessary output value, then push
. For
example, to source 5.5 V dc, push
5
