Installation; Introduction - Fluke RUSKA 2465A-754 User Manual

Introduction

Numeric references are to drawing RUSKA 2465A-754, contained in Appendix B.
The gauge should be installed in a room where the temperature is maintained between
18 ºC to 28 ºC. The actual temperature is not as important as the stability in temperature.
There should not be excessive personnel traffic and air drafts. Airborne dust is
undesirable, but clean-room standards are not required.
Remove the gauge from its shipping box and locate it on a clean, level, sturdy work
surface. The surface should be able to support fifty pounds of weight without deflecting
and be secure enough to be free from vibration. Level the base by turning the two
leveling screws (0003) until the bubble in the level vial is centered.
Refer to plumbing connection diagrams in Appendix B or to instructions in operating
manual for pressure controller for proper connections to the gas source and to the test
instrument. The motor unit on the Piston Pressure Gauge is designed to operate on either
115 VAC or 230 VAC; 50 or 60 Hz. After determining what the local power line voltage
is at the intended location of operation, select either 115 VAC or 230 VAC by the proper
positioning of the voltage selector on the side of the motor unit. This feature is located on
the power inlet module. With power cords disconnected to both Piston Pressure Gauge
and wall outlet, use a small screwdriver to pry open the voltage select/fuse compartment
on the power inlet module. Place two fuses of the correct value, depending on local
power supply conditions, into their fuse holders inside the power inlet module. Remove
the voltage select wheel and turn it so that when it is replaced into the fuse compartment
and the door is snapped shut, the correct voltage is displayed through the window. Plug
the unit into a grounded 115 VAC or 230 VAC; 50 or 60 Hz power outlet capable of
handling 15 watts of power using a proper power cord suitable to the voltage.
DO NOT attempt to turn the voltage select wheel while it is still
in place within the fuse compartment. Always remove it first
from the compartment and then replace it. Turning the wheel
while in place may damage the electrical contacts.
If the gauge is being used with an electronic thermometer, insert the probe into the hole
on the back left side of the base. A small amount of heat sink compound on the tip of the
probe will shorten the response time of the temperature sensor.
