The Model 230 operates from either two 9 Volt batteries or the included 90-240VAC, 50/60Hz universal power module. An LED BAT LO indicator is located on the front panel. A 36” (92cm) shielded Teflon® BNC-BNC low leakage cable for connection to the ETS family of Faraday cups, buckets and probes is also included.
Model 230 Nanocoulombmeter: A battery/AC powered instrument for measuring charge directly in nanocoulombs (nC). User selectable ranges of 20, 200 and 2000nC cover most triboelectric charge measurement requirements. An integrated 1.00V calibration source is used to charge the supplied 0.1μf, 1% capacitor to enable system calibration to be checked at any time. Using the relationship Q=CV, 1V across the 0.1μf capacitor results in a charge of 100nC.
A 3½-digit LCD meter provides 0.01nC resolution in the 20nC range. The REMOTE output jack on the rear panel enables the Nanocoulombmeter ZERO/READ function to be controlled with an optional foot switch that is extremely useful when performing sensitive measurements inside a controlled environment chamber or when performing multiple tasks.
