Math Operations
There are two math operations available, only one of which can be enabled at a
time. You can choose to either scale the readings as they are taken, or keep
statistics on a group of readings. The selected math operation remains in effect
until you disable it, change functions, turn off the power, or perform a remote
interface reset.
Scaling
– The scaling is applied as:
reading = gain * (measurement - offset)
– Front Panel operation: Set the values of gain and offset in the MATH menu.
Enable scaling by pressing the scale key. The Stats annunciator will light in the
display.
– Remote operation: the math operations and registers are controlled using
commands within the CALCulate command subsystem. First, select the math
operation you want to use
CALCulate:FUNCtion SCALe
Then, set the values for gain and offset.
CALCulate:SCALe:GAIN <gain>
CALCulate:SCALe:OFFSet <offset>
Finally, enable the selected math function by turning the math state on:
CALCulate:STATe ON
