MultiCal Instruction Sheet

kPa/PSI Pressure Module

Introduction

MultiCal pressure modules are used to measure pneumatic or hydraulic pressures. They can

also be used to measure vacuum.

MultiCal modules don’t display

pressure, since they only have

an electrical output. Instead, the

modules convert pressure to

millivolts. Modules are used with

devices capable of measuring

DC millivolts, such as a digital

multimeters or oscilloscopes.

MultiCals are calibrated to convert

pressure units (for this model, inches kPa

or PSI) to 1 millivolt per pressure unit. Vacuum

readings will of course be negative.

Pressure is measured by connecting an appropriate ﬁtting to one of the two

″ female NPT

ports (plug any unused port). Any gas or liquid compatible with 316 stainless steel, PTFE

(polytetraﬂuoroethylene) impregnated hard anodized aluminum, and buna-n rubber, can be

applied to the module as the pressure source.

The three-position switch acts as a power switch as well as selecting kPa or PSI scaling

for the output. The OFF position is used to measure the internal battery condition via an

external multimeter.

MultiCal modules perform best when used with high accuracy multimeters. We recommend

meters manufactured by the Fluke Corporation, but MultiCals can be used with any meter

that has 10MΩ or greater input impedance, and (preferably) 4mm banana jacks on 19mm

(

″) centers.

When used with a high performance multimeter, the pressure adapter becomes more

than just a “digital pressure gauge”. By using the features built-in to the Fluke 87 for

example, the system becomes a datalogger capable of measuring and recording peak high,

peak low and average pressures.

This manual includes instructions for calibrating the module itself, but we also offer repair,

calibration/certiﬁcation services. MultiCals are manufactured (and serviced) by a company

that only makes pressure measuring instruments. It’s the only thing we do and that’s why we

say: Pressure is Our Business!
