Preparation; Introduction; Operating Fluid - Fluke P3100 Series User Manual

Introduction

The deadweight tester must be set up on a level, stable workbench or similar surface.
Remove spokes from tool roll and fit to capstan hub.
Level the tester using the four adjustable feet to the bubble level attached to the top plate.
Rotate reservoir dust cover through ¼ turn and fill reservoir approximately ¾ full with
the appropriate fluid. Rotate dust cover back to cover hole.

Operating Fluid

Oil: The instrument is supplied with Shell Spindle Oil 22, our reference 55-655.
Water: Only Distilled or De-ionized Water should be used in the instrument. Great
care must be taken when operating any deadweight tester that uses water as its operating
fluid, as any contamination present within the system will result in degradation of
performance, and eventual irreparable damage to the PCUs. The impurities found in
ordinary water supplies are sufficient to affect the spin and sensitivity of the PCU
assemblies, and damage the PCUs.
The system is designed for use with the fluids described above
only; use of other fluids can effect the operation and
performance of the instrument, and CAN CAUSE PERMANENT
DAMAGE.
To avoid damage to the instrument, the operator should check
the quality of the operating fluid during use. If the fluid
becomes discolored, cloudy or particles appear in the reservoir,
the system should be drained and flushed with clean fluid.
If the device under test (DUT) is from a system operating on
different fluid from that of the deadweight tester, the Liquid
Separator, P5521, can be mounted to the test port of the
deadweight tester. This will allow the calibration of the DUT in
its normal operating fluid, and prevent cross-contamination of
the system, (See Chapter 9, Ancillary Equipment, Liquid
Separator).
