Jandel RM3000 Test Unit

The RM3000 Test Unit is a specialty electronics instruments designed specifically for the four point probe measurement. It features high accuracy, an excellent range, and many features which simplify the four point probing measurement. Jandel RM3000 Test Unit with PC Software

Combined Constant Current Source and Digital Voltmeter Designed

Specifically for the Four Point Probe Measurement

The following are features of the RM3000 Test Unit:

The sheet resistance range of the RM3000 Test Unit is from 1 milliohm-per-square (10^-3) up to 5 x 10^8 ohms-per-square with 0.3% accuracy. The volume resistivity range is from 1 milliohm-cm (10^-3) up to 10^6 ohms-cm, however, that resistivity range refers to measuring a bulk material directly as opposed to measuring a thin film and converting to volume resistivity using the software. For example, a thin layer of copper (1.68 x 10^-6 ohm-cm) up to about 16 microns thick can be measured. The RM3000 can determine the volume resistivity value if one enters the film thickness.

The RM3000 PC control software which can be downloaded online and used for measurement logging (storing data in CSV format) and can save measured values as sheet resistance or volume resistivity.

The RM3000 display reads-out the input current as well as either ohms-per-square (sheet resistance), ohms-cm (volume resistivity), or millivolts, without requiring the use of the included PC software. The volume resistivity readout requires entering thickness for a wafer or thin film, or tip spacing if measuring a bulk sample.

The RM3000 has onboard non-volatile memory so that up to 50 measurements can be stored internally and then downloaded and saved all at one time using the software. Alternately, each measurement can be saved to a PC as it is made using the included software.

The RM3000 has an auto-range button that can be used to automatically determine the optimum input current for a given material without using the trial and error method.

The RM3000 has forward (FWD) and reverse (REV) buttons to reverse the direction of current flow. A common way to determine if a measurement is valid is to reverse the direction of current flow and then check to see if the forward and reverse voltage readings correlate well, i.e., the values should be similar, but with the reverse current voltage being a negative value.

The RM3000 allows the input of a correction factor for samples that need to be corrected for size.

The RM3000 has a date and time stamp feature

The RM3000 interfaces with optional AFPP motorized Z-motion arm
