Model 2700 Multimeter/Switch System User’s Manual Basic DMM Operation 3-47
Continuity testing
The instrument can test continuity using the 2-wire 1kΩ range. After selecting continuity,
you will be prompted to enter the threshold resistance level (1 to 1000Ω). When the
measured circuit is below the set threshold level, the instrument will beep and display the
resistance readings. When the measured circuit is above the threshold level, the unit will
stop beeping and it will display the resistance value. For instance, if the measured circuit is
out of range of the continuity function (that is, greater than 1.1KOhm), the message
“OPEN” will be displayed. If the reading is below 1100Ω, it will be displayed. If the
reading is 1100Ω or above, “OPEN” will be displayed.
NOTE The reading rate for continuity is fixed at FAST (0.01 PLC).
Limits and digital outputs cannot be used when testing continuity with the
continuity (CONT) function. If you need to use these operations, use the Ω2
function to test continuity.
Connections
NOTE When using the front panel inputs, the INPUTS switch must be in the “F” (out)
position. For switching modules, it must be in the “R” (in) position.
Front panel input
When using the front panel input terminals, connect the test leads to the INPUT HI and
LO terminals as shown in
Figure 3-19A.
Model 7700 switching module
Connections for the Model 7700 switching module are shown in Figure 3-19B. Since this
is a 2-wire ohms measurement, channels 1 through 20 can be used.
