Powerful features
Bin sorting function
Quickly sort components using the 10 bins of the 2841 or 3 bins of the 2840.
The results can be displayed on the screen or output via the handler interface.
High and low limits for each bin can be set up in absolute or tolerance mode.
Temperature correction
The 2841 can compensate for temperature changes with a component’s known
temperature coefficient of resistivity. This allows for increased comparison
accuracy between components that are measured at different temperatures.
Remote PC control
Integrate your DC resistance meter into an automated test system and control
it from a PC using commands via the RS232 or USB interface. The 2841 is
LAN enabled with a web browser interface that allows users to conveniently
configure, control, or monitor basic settings.
Component testing
Measure the resistance of motor and transformer windings, relay and
switch contacts, and other conductive materials and components. 4-wire
Kelvin test leads included with both models.
Circuit board testing
The resistance meters’ high accuracy make them suitable for measuring
trace resistances and finding shorts on PCBs.
Applications
LPR (Lower Power Resistance) measurement
In standard resistance measurement mode (LPR OFF), the large drive current
(1 A max.) may damage sensitive components or circuits. LPR mode protects
the DUT by limiting the maximum power being applied.
Offset voltage compensation (OVC)
OVC switches the polarity and averages the forward and reverse polarity
readings. This enables accurate measurements by minimizing the adverse
effects of thermal EMFs or small biases in a circuit (e.g., from a capacitor’s
dielectric absorption when measuring a PCB trace).
