The Model 2500 display is used primarily to display measured readings and voltage bias
source values. The top line displays measurement function readings, and the bottom line
shows voltage bias values. Channel 1 measurement function readings (MSR1) are dis-
played on the left, while channel 2 measurement function values (MSR2) appear on the
right. (You can select channel 1, channel 2, or dual-channel display with the CHANNEL

Measurement reading information can be displayed using either engineering units or sci-
entific notation in either fixed- or floating-point format. Use the GENERAL/NUMBERS
selection of the main MENU to select the display format, as discussed under
later in this section.
