RM3000 Test Unit Instructions
The RM3000 is a combined constant current source and digital voltmeter. It
has been designed for use in making resistivity measurements in
combination with four point probe equipment. The unit supplies a constant
current and can display the resultant voltage, sheet resistance or volume
resistivity depending which function has been chosen. For calculation of
volume resistivity it is possible to input wafer thickness or probe spacing as
required.
Unpacking
When you unpack the RM3000 you should find:
1) A Jandel RM3000 Test Unit
2) A power lead
3) A 100 ohm test resistor
4) A green case key which can be used to open the RM3000 cabinet (not
recommended)
5) A copy of the RM3000 software for computer control and exporting
of results
6) A USB lead
Getting to know the RM3000
On the RM3000 you will find the display area:
This is where the current being used is displayed, the direction of the current
and the output in mV, ohms/square and ohm.cm.
