Input HI and LO connectors
.
Input connectors for Volts, 2-wire Ohms, Hz, Period
,
Temperature
,
and Capacitance
measurements.
Input connectors source current for 4-wire Ohms
measurements. All measurements use the Input LO connector as a common input. The LO input
is isolated, and may be safely floated up to 1000 V above earth ground regardless of the
measurement type
.
1000 V is the maximum voltage rating between the Input HI and LO
connectors and between each HI and LO input and earth ground.
®
Sense HI and LO connectors. Sense connectors sense the voltage across the unknown
resistance for 4-wire Ohms measurements or provide the DCV reference Input for DCV Ratio
measurements.
@
Soft keys F1 through F5. Soft keys are used to select various menu options while 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
8)
Memory key for accessing internal and external memory containing meter setups and
measurements.
See the "Accessing and Controlling Memory" section for more information
.
®
USB Port
.
Connection for USB memory device that can be used to store meter readings
(memory device not included).
®
Standby key to turn off the
display.
While in standby, the Meter will not respond to remote or
front-panel commands. When taken out of standby, the Meter sets itself to its power-up
configuration
.
(])
Instrument Setup
key.
Accesses communication interface selection and setup, remote command
set, system settings, and meter reset.
®
Measurement Setup key. Accesses to resolution setting
,
trigger functions, temperature
setup,
dBm reference selection
,
continuity settings, and other measurement related parameters.
®
Trigger key. Triggers measurement when trigger is set to external triggering
.
See the
"Controlling Trigger
Functions"
section later in this chapter to learn how to use the trigger key
(TRIG) to control the Meter's measurement cycle.
@
Analyze
key.
Accesses math functions
,
Statistics,
TrendPlot, and Histogram
.
@
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 ac
, ohms,
continuity, diode
test,
frequency, period, capacitance
[11.
and temperature (11 For the 4040, the
lower four keys select different functions

inset.
@
Range keys. Selects between manual and auto range mode. Also increases or decreases the
range when in manual ranging
mode.
@
Back
key.
Backs up one layer in the menu selection
.
@
Front and Rear input switch. All front-panel input connectors
,
except 10 A, are available on the
rear-panel of the Meter. These switches switch the Meter's input between them
.
@
400 mA and 10 A input connectors for ac and dc current measurement functions
