EVOM3
World Precision Instruments 5
STX2-PLUS Features
• STX2-PLUS new electrode designed for 12 and 24-well plates.
• Weighted self-standing electrode for hands free stable measurements
• Shielded cable to minimize electrical and cell phone interference
STX2-PLUS Benets
• Keyed electrode base for repeatable placement gives more consistent results
eliminating the need for multiple readings.
• Easy to maintain
Notes and Warnings
Choice of current/range: The EVOM3 has three ranges of current from 2 µA to
and eah ent ange ha it n eitie e limit t K Ω
• K Ω ange
• K Ω ange
• K Ω ange
The auto range will adjust the current as needed from 2 µA to 10 µA depending on
the resistance.

Use of the charger: The EVOM3's Li-ion battery will last 8 hours on its own. The
haging time i h ith the nit eed he EVOM3 charger should not
be plugged in all the time. The chager may be used to power the EVOM3 for normal
and long-term use.
NOTE: In the higher resistance ranges (50K -100K ) there may be a slight instability
added from the noise of the power supply, in that case unplug it during those
measurements.
USB Drives: WPI has supplied a tested USB thumb drive. Most drives of 32 Gb
(USB2.0) or smaller sizes have been tested.
CAUTION: Not all USB drives work on the EVOM3.
To test a USB drive, see "Sample Resistance File (*.CSV)" on page 16. This test saves

drive is usable, or it will display an error. If the USB thumb drive is not plugged in or
it is not recognized, a warning message will appear. Press

and try again. The
