O
The power switch turns the power on and off. The switch is a latching push-push type. When the
switch is latched in, power is on.
P
m
The MORE MODES key provides access to the measure pressure function. You need a Fluke
700 Series pressure module to measure pressure.
Q
D
The DIV (Divide) key immediately changes the output to 1/10th reference value (not necessarily
the present output value) if the value is within performance limits. In the SCOPE mode, the DIV
key changes the output to the next lower range.
R
X
The MULT (Multiply) key immediately changes the output to 10X the reference value (not
necessarily the present output value) if the value is within performance limits. This key sets the
5520A to standby if this change is from below 33 V. In the SCOPE mode, the MULT key
changes the output to the next higher range.
S
U
The MEAS TC (Measure Thermocouple) key enables the TC (Thermocouple) input connection
and causes the 5520A to compute a temperature based on the voltage present at the input.
T
Output Units Keys
The output units keys determine the function of the 5520A. Some keys have a second unit if the
SHIFT key is pressed just before the units key. The output units are as follows:
V Voltage or Decibels relative to 1 mW into 600 ohms
(impedance changeable).
A Watts or Current
Q Resistance
H Frequency or Seconds (Seconds is applicable to the SCOPE
functions only)
F Capacitance
C Temperature in Fahrenheit or Celsius
When a frequency (Hz) value is entered, the 5520A automatically switches to ac. When a new
signed (+ or −) output value is entered without specifying Hz, the 5520A automatically switches
back to dc (or enter “0” Hz to move back to volts dc).
U
Multiplier Keys
Select output value multipliers. Some keys have a second function if the SHIFT key is pressed
just before the multiplier key. For example, if you enter 33, then SHIFT, then c, then F,
then ENTER, the 5520A output value is 33 pF. The multiplier keys are as follows:
c milli (10
-3
or 0.001) or micro (10
-6
or 0.000001)
K kilo (10
3
or 1,000) or nano (10
-9
or 0.000000001)
M mega (10
6
or 1,000,000) or pico (10
-12
or 0.000000000001)
