The
=i
and
t
keys adjust the magnitude of changes by moving the highlighted digit. The
É
key allows you to move from voltage or current to frequency and back. In practice, for
voltage and current outputs, the knob and arrow keys are used to adjust output until the UUT
reads correctly. The error display then displays UUT deviation from the reference.
O
The
POWER
(Primary Power) switch turns the power on and off. The switch is a latching push-
push type. When the switch is latched, power is applied.
P
^
The
AUX INPUT
key allows you set the calibrator to AUX INPUT mode which passes the signal
present at the AUX INPUT connector to the selected output channel.
Q
a
The
DIV
(Divide) key immediately changes the output to one tenth the reference value or the
next lower cardinal value, depending on the mode.
R
u
The
MULT
(Multiply) key immediately changes the output to ten times the reference value or the
next higher cardinal value, depending on the mode.
S
`
The
CHANNEL
key lets you select the different available channels with the 5-channel option.
T
k
The
NEW REF
(New Reference) key is active during error mode operation, and establishes the
present output value as a new reference for UUT error computation
U Output Units Keys
The output units keys determine the function of the 5820A. The output units are as follows:
s e
_ Ç
When you enter a frequency (Hz) value, the 5820A automatically switches to ac. When you
enter a new signed (+ or -) output value without specifying Hz, the 5820A automatically switches
back to dc (or enter “0” Hz to move back to volts dc).
V Multiplier Keys
Select output value multipliers. The multiplier keys are as follows:
Å
milli (10 -3 or 0.001)
r
micro (10 -6 or 0.000001)
h
kilo (10 3 or 1,000)
å
nano (10 -9 or 0.000000001)
j
mega (10 6 or 1,000,000)
