1. General Introduction
Manual Conventions
This manual is intended to provide the user with the basic information necessary to operate a
PDR1000 (Digital Pressure Gauge). It also includes a great deal of additional information provided
to allow you to optimize PDR1000 use and take full advantage of its many features and functions.
“Caution” is used in throughout the manual to identify conditions or actions that could
cause harm to the PDR1000 or user of the PDR1000.
“Note” is used throughout the manual to identify operating and applications advice
and additional explanations.
High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and
gases can be released unexpectedly and with extreme force. High pressure systems should be
assembled and operated only by authorized personnel who have been instructed in proper safety
practices.

3. Introduction
The PDR1000 Series Reference Digital Pressure Gauges (the Product) are high accuracy digital
pressure test gauges. PDR1000 has best performance that can measure precision pressure from
-100 kPa to 500 MPa without a separate external power supply in anytime any place, including
on-site and laboratory. Also PDR1000 equipped solid and stylish aluminum outer casing for
durability.
PDK produced PDR1000 with PDK’s unique pressure calibration and production technology
that has best performance in its class. PDR1000 is digital pressure gauge for precise pressure
measurement and test with Built-in various features.
Simply use buttons on front panel to operate and select various functions and external power
input section, analog output port (1 to 5 VDC), and communication port (RS232) and batteries
change socket on rear panel.
Combine pressure comparator or hand pump for using pressure calibrator in field and calibration
lab for simple pressure measurement and calibration provides an excellent solution.

4.1 Key Operation
4.1.1 Power On
: Push POWER key on front panel to power on.
Screen at no pressurize or Zero set.
4.1.2 PEAK / MENU
: Peak shows maximum and minimum pressurized value on PDR1000.
Push PEAK/MENU key indicates Hi for maximum pressurized value.
Push PEAK/MENU key again, indicates Lo for minimum pressurized value.
Push PEAK/MENU key again, return to the current pressure value.
4.1.3 UNITS
: This function can change engineering units on PDR1000.
When push UNIT key engineering units will change as following steps.
MPa →mbar →bar →inH2O →mmH2O →inHg →mmHg →kgf/cm² →atm
→psi →kPa →MPa
To set Analog Out function, push UNIT key for 2 seconds.
(It only operates when external power supply connected)
