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
