Model 2750 Multimeter/Switch System User’s Manual
Rel, Math, Ratio, Channel Average, dB
5-9
mX+b
This math operation lets you manipulate normal display readings (X) mathematically
according to the following calculation.
Y = mX + b
where:
X is the normal display reading.
m and b are the user-entered constants for scale factor and offset.
Y is the displayed result.
NOTE
When using Rel, the rel’ed reading of the input signal is used by the mX+b
calculation.
mX+b configuration
1.
Press SHIFT and then MATH to display the math menu.
2.
Press the RANGE
Δ
and
∇
key to display “mX+b”, and press ENTER to display
the present scale factor:
M: +1.000000
Δ
(factory default)
3.
Key in the scale factor value. The
and
keys control cursor position, and the
Δ
and
∇
keys increment/decrement the digit value. To change range, place the cursor
on the multiplier and use the
Δ
and
∇
keys (m =
×
0.001,
Δ
=
×
1, K =
×
1000,
and M =
×
1,000,000). With the cursor on the polarity sign, the
Δ
and
∇
keys tog-
gle polarity.
4.
Press ENTER to enter the M value and display the offset (b) value:
b: +00.00000 m
(factory default)
5.
Key in the offset value.
6.
Press ENTER to enter the b value and display the one-character units designator:
UNITS: X
(factory default)
7.
Use the cursor keys and the
Δ
or
∇
key if you wish to change the units designator.
The character can be any letter in the alphabet (A through Z), the degree symbol
(°), or the ohms symbol (
Ω
).
8.
Press ENTER. The MATH annunciator will turn on, and the result of the calcula-
tion will be displayed. Note that the calculation will be applied to all measurement
functions.
9.
To disable mX+b, again press SHIFT and then MATH. The MATH annunciator
will turn off.
