8845A/8846A Users Manual B Sense HI and LO connectors. Output connectors to source current for 4-wire Ohms measurements. Soft keys F1 through F5. Soft keys are used to select various menu options while C navigating the Meter's menus. Each soft key's function is identified with a label in the bottom row of the display. Keys without a label above them are inactive Memory key for accessing internal and external memory[1] containing meter setups and D measurements. See the "Acessing and Controlling Memory" section for more information. E USB Port. [1] Connection for optional memory device to store meter readings. Standby key to turn off the display. While in standby, the Meter will not respond to F remote or front-panel commands. When taken out of standby, the Meter sets itself to its power-up configuration. G Instrument Setup key. Accesses communications interface selection and setup, remote command set, system settings, and meter reset. Measurement Setup key. Access to resolution setting, trigger functions, temperature H setup, dBm reference selection, continuity settings, and other measurement related parameters. Trigger key. Triggers measurement when trigger is set to external triggering. See the I "Controlling Trigger Functions" section later in this chapter to learn how to use the trigger key (TRIG) to control the Meter's measurement cycle. J Analyze key. Accesses math functions, Statistics, TrendPlot, and Histogram. K Zero key. Uses the present reading as an offset value to create relative readings. Meter function keys. Selects meter function between volts dc, volts ac, amp dc, amps L ac, ohms, continuity, diode test, frequency, period, capacitance [1], and temperature .[1] For the 8845A, the lower four keys change functions; see inset. M Range keys. Selects between manual and auto range mode. Also increases or decreases the range when in manual ranging mode. N Back key. Backs up one layer in the menu selection. O Front and Rear input switch. All front-panel input connectors, except 10 A, is available on the rear-panel of the Meter. These switches switch the Meter's input between them. P 100 mA and 10 A input connectors for ac and dc current measurement functions. Notes: [1] Available on 8846A only Display Panel The display panel described in Table 3-2, performs the following three functions: • Displays measurements as a value, with measurement units, and measurement statistics in both numerical and graphical format (TrendPlot and Histogram). • Displays soft labels for soft keys, F1 through F5. • Identifies the current mode of operation, Local (MAN) or Remote (REM). 3-4
