INTRODUCTION
PURPOSE OF EQUIPMENT
The 233 is a dedicated non-destructive plating thickness tester. It is designed to
precisely measure nonconductive coatings on conductive substrates and/or
nonmagnetic coatings on magnetic substrates.
LOCATION OF INSTRUMENT
The 233 is a hand-held plating thickness gage designed to be used in a shop
environment. All cable connections are covered to prohibit foreign matter from
getting into the unit. The carrying case provides additional coverage of any
openings on the unit.
ELECTRICAL CONNECTIONS
Each 233 operates from a 9-volt battery or a low voltage power supply connected
to a 115-volt, 50/60 Hertz, single-phase alternating current power source. If a
battery is the source of power to the gage, when the battery voltage drops below
the level required for operation a low battery condition will occur. The unit will
show “BAT” in the lower right of the display. The battery should be replaced with
an alkaline type before the unit will function properly.
SETUP
UNPACKING
Carefully open and inspect the shipping box, and remove all items. Notify Oxford
Instruments and/or the carrier immediately in case of damage to the unit.
CABLE CONNECTIONS
There are three connectors provided at the top on the unit. Each cable
connection to the 233 is unique to prevent incorrect connection. There is a
phone type jack for connection of the printing or serial dump cable, a jack for the
connection of a low voltage power supply, and a polarized 6 pin threaded
connector for the probe. Connection of any other external device may damage
the gage.
POWER ON/OFF
The unit can be turned on at any time by pressing the ON/OFF key. The
ON/OFF key turns off the unit or it will turn off automatically after ten minutes
have passed and no entry or measurement has been made. When the unit is
turned on, the software version will show in the upper left of the display and the
model number will flash in the main display. After this, the display will show the
last reading taken in the main display and the memory location in the upper left of
the display.
