1586A Users Manual Table 3-10. Math Channel Formulas (cont.) Formula Equation Description 1 / A 1 / A Calculates the reciprocal of a variable. The argument cannot be 0 or the result will be "+OL". A + B A + B Adds the readings of two source channels. This is useful to create expressions of more than one independent variable. A - B A - B Calculates the difference between readings of two source channels. A x B A x B Multiplies the readings of two source channels. This can be useful for calculating electric power from a voltage reading on one channel and a current reading on another channel. A / B A / B Divides the reading of one source channel by the reading of another channel. This can be useful for observing the ratio of two related parameters. The argument cannot be 0 or the result will be "+OL". Average [1] Maximum [1] Minimum [1] Sum [1] A1 + A2 + A3... N N/A N/A A1 + A2 + A3... Calculates the arithmetic mean of the readings of selected channels. Finds the maximum reading among selected channels. Finds the minimum reading among selected channels. Calculates the sum of the readings of selected channels. Note [1] - Maximum of 10 channels can be calculated. Set up a math channel as follows (see Table 3-11): 1. Connect and configure the channel or channels to apply the math formula to. 2. Set the channel to ON (see "Set Channels to ON or OFF" on page 3-12). When the channel is set to ON, a channel configuration sequence shows on the display that steps the user through an initial configuration sequence as shown in Table 3-11. If the channel was previously configured, push  to cancel the configuration sequence to use the last channel configuration. 3. Use the information in the Table 3-11 to configure the math channel. Push  or  to highlight the channel setting then push  to edit the setting. 3-28 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664

Table 3-10. Math Channel Formulas (cont.)
Formula
Equation
Description
1 / A
1 / A
Calculates the reciprocal of a variable. The argument
cannot be 0 or the result will be "+OL".
A + B
A + B
Adds the readings of two source channels. This is useful
to create expressions of more than one independent
variable.
A – B
A – B
Calculates the difference between readings of two
source channels.
A x B
A x B
Multiplies the readings of two source channels. This can
be useful for calculating electric power from a voltage
reading on one channel and a current reading on
another channel.
A / B
A / B
Divides the reading of one source channel by the
reading of another channel. This can be useful for
observing the ratio of two related parameters. The
argument cannot be 0 or the result will be "+OL".
Average
[1]
A1 + A2 + A3…
N
Calculates the arithmetic mean of the readings of
selected channels.
Maximum
[1]
N/A
Finds the maximum reading among selected channels.
Minimum
[1]
N/A
Finds the minimum reading among selected channels.
Sum
[1]
A1 + A2 + A3…
Calculates the sum of the readings of selected channels.
Note
[1] - Maximum of 10 channels can be calculated.
Set up a math channel as follows (see Table 3-11):
1.
Connect and configure the channel or channels to apply the math formula to.
2.
Set the channel to ON (see “Set Channels to ON or OFF” on page 3-12). When the
channel is set to ON, a channel configuration sequence shows on the display that
steps the user through an initial configuration sequence as shown in Table 3-11. If the
channel was previously configured, push
to cancel the configuration sequence
to use the last channel configuration.
3.
