CONVERSION
RATE
(6
)
fast
With this
button illuminated, the
conversion (read
ing)
rate is the maximum rate specified for the se
lected
measurement function. At this conversion
rate, resolution is 3.5 digits.
When the
FAST button is not illuminated, conver
sions occur
at the
normal reading rate specified for
the
selected measurement function. Results
are
displayed using 4.5 digits.
(7)
AVERAGE
Illuminating this
button causes the DM 5010 to
cal
culate the average of a series of
readings. The val
ue
of
the N constant determines how many
readings
are averaged in the series. To calculate
the
average, the instrument
sums the measured
values
for the series of readings and divides the
sum by
the number
of readings in the series. If
LOW FREQ RESPONSE is also
active, the number
of
measurements
averaged is
four times the value
of
the N constant. When operating in the TRIG
GERED mode, only one trigger is
required to initi
ate
all the measurements used in the AVERAGE
calculation.
N
This
button is
used to store or recall a constant
used
in
the
AVERAGE calculation. The constant
determines how
many measurements are aver
aged.
At
instrument power-up, the value of N is set
to
2. This value can be changed to any positive
integer
>1 and
< 19999.
(8) X-B / A
Illuminating
this button causes the DM5010 to
subtract a
stored offset constant from a measure
ment, divide
the result
by
a
stored scale constant,
and display
the result.
The offset constant is B, the
scale
constant is A,
and X is the measurement.
A,
B
These buttons are used to store or recall constants
used in the X-B/A calculation. At
instrument power-
up,
the value
of A is set to 1
and the value of B is
set to
0. These constants can be changed to any
number
(integer, decimal, positive or negative) ex
cept that the value of
A cannot
be 0.

)
dBm
When this
button is illuminated, the DM 5010 cal
culates and displays the
power ratio of a voltage
measurement referenced to
1 mW and 600 Ω
(.7746
V), using
the formula:
dBm
= 20 logw i x1 i
IT
b
I
where x
is
the voltage measurement. The loga
rithm of the absolute value of
x
/\/3>
is taken.
dBr
When this button is illuminated,
the DM 5010 cal
culates
and
displays
the
logarithmic ratio
of
a
mea
surement to
the constant
stored for the ref button,
using
the
formula:
dBr =
20 logw
where
xi
is the measurement.
The logarithm of the
absolute
value
of x
/ref is taken.
ref
This
button is used to store or recall a constant
used in
the dBr calculation. At instrument power-
up,
the value of
ref is set to 1. The value of ref can
be any number except 0.
(10) COMPARE
Activating
this
calculation (button
illuminated)
causes
the
DM 5010 to
compare the next reading
with
limits set
by LIMITS constants. If the com
pared reading is
algebraically less
than both
constants, the
word LO is displayed.
The word HI
is
displayed
if the reading is algebraically greater
than
both constants. PASS is displayed if the read
ing is equal to or between the constants.
LIMITS
(2)
These
buttons are used to store or recall constants
used as
limits in
the COMPARE calculation. The
values
of
the constants are
set to
0 at instrument
power-up.
(11)
RECALL CONST
Pressing this button and then one of the constant
buttons
(N, A, B, ref, LIMITS) causes the instru
ment to display the value
stored for that
constant.
(
12
) REAR INPUT
Δ
See
Rear
Interface Measurements
under
Opera
tors Familiarization
in this section of the manual.
Illuminating
this
button
selects rear-interface inputs
instead
of front-panel inputs.
(13)
DIGITS
(0 through 9), Decimal Point,
and Sign
These
buttons are used for entering numerals,
decimals,
and
polarity for
storing
constants.
CLEAR
When an error code is displayed
in the display win
dow, activating this button clears the displayed er
ror
code.
Also,
when
entering a constant, acti
vating
the CLEAR button clears from the display
window
a
constant value that has not yet been
entered.
ENTER
When
entering a constant, activating this button
stores
the number for the selected constant and
displays
the
stored constant value.
