Product Description

Ultra-Stable Isoprobe Rack Mountable Voltmeter, 300V

279_newModel 279L Ultra-Stable Isoprobe Rack Mountable  Voltmeter

This instrument is a Model 279 with its input range limited to +or- 300V (instead of +or- 3kV) through the use of an alternative high voltage power supply and amplifier section.  This alteration produces an instrument with improved noise characteristics and meter resolution and less proclivity toward arcing at extremely close probe-to-surface spacing.

Thus, the Model 279L is better able to take full advantage of Model 1034 probes where the restricted voltage range is acceptable.  This is particularly useful in areas of ESD monitoring and control.  Some typical and potential applications include:

*  Disk Media Research

*  IC Manufacturing and Handling

*  Contact Potential Measurements

*  Radiation Effects on Insulators and Semiconductors

*  Bioelectric Field Studies

Feature 1: Low profile half rack size for multichannel applications
Feature 2: Full complement of interchangeable probes
Feature 3: 100mV resolution
Specification:

Size 1.7 x 8.2 x 15.1 inches (44 x 208 x 384mm), 1.75″ rack mounting available (1  or 2 per rack).
Weight 4 lb. (1.8kg)
Power Requirements 100, 115, 230 VAC, ±10%, 50/60Hz, 15 watts.
Meter Range ±300 volts
Step Response: For typical input step: <3ms (10% to 90%)
Surface Resolution: Determined by probe aperture size and surface-probe separation. Standard  type 1034E & 1034S probes with 0.07″ (1.75mm) aperture will resolve a 0.10″  (2.5mm) spot at 0.02″ (0.5mm) separation.
Drift: <0.01V/hr
Noise: 90mV rms referred to input typical.
Recorder Output 100:1, +or- 3volts full scale
Display Type: LED meter
Accuracy 0.1% or 10mV whichever is greater,
