Operating the Meter From the Front
Panel
Introduction
Chapter 3 explains how to operate the meter from the front panel. Refer to Chapter 4 for
information concerning specific applications. Chapter 5 provides instructions on how to
operate the meter using the computer interface (RS-232 or IEEE-488).
Front Panel Operations
The following operations can be performed from the front panel:
• Select a measurement function (volts dc, volts ac, current dc, current ac, resistance,
frequency, and diode/continuity test) for the primary and secondary display.
• Take a measurement and display a reading.
• Select the manual or autorange mode (AUTO).
• Manually select a measurement range for the primary display.
• Select function modifiers that cause the meter to display relative readings (REL),
minimum or maximum values (MN MX), or decibels (dB), or to enter the Touch
Hold mode (HOLD) to hold a reading on the primary display.
• Change the measurement rate (slow, medium, fast).
• Set the dB reference resistance (REF Ω).
• Take a measurement and compare (COMP) it against a tolerance range (HI, LO, or
PASS).
• Use the "editor" to select from option lists, to enter a relative base, or to enter a HILO
range for the compare (COMP) mode.
• Configure the computer interface (RS-232 or IEEE-488).
• Take an audio power reading.
• Send measurements directly to a printer or terminal through the RS-232 interface
(RS-232 print-only mode).
These and other front panel operations are described in the remainder of Chapter 3.
