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.

Pressure Switch Test function is that receive and indicate Electric contact signal (On/Off) from
Pressure Switch.
Push PEAK/MENU key for 2 seconds to go to Menu function then select Switch Menu screen.
Push ZERO key to set Switch On or Off. Push Enter key to save Switch status then escape the
Switch Menu.

1) Operation for External Pressure Switch Off to On
Pressure Switch function “ON” screen on above.
If PDR1000 received external electric contact signal (Switch turns Off to On)
2) Operation for External Pressure Switch On to Off
Switch icon will change from open to close ( ) then pressure value will be hold status
with “Hold” icon blinking. Even supply pressure changed, Pressure value will keep hold until push
ZERO key. Pressure changes can check via percentage section on the bottom side of screen.
This case is that external electric contact open to close – in other words switch status changed
from Off to On.
The other case is switch turns from On to Off.
If it connect with Switch “On” status, it will be “1)” operation because initial status of Switch function
is open icon as ( ).
If push ZERO key, it will be same screen as on below screen.

If PDR1000 received external electric contact signal (Switch turns On to Off), Switch icon will
change from close to open ( ) then pressure value will be hold status with “Hold” icon

Even supply pressure changed, Pressure value will keep hold until push ZERO key.
Pressure changes can be checked via percentage section on the bottom side of screen.
<Hysteresis function>
Apply Switch function operation with Switch “On” status then connect External Pressure Switch
to PDR1000.
If pressure value reach the Pressure Switch set value, display pressure value will be hold then
copy down the held pressure value.
Push ZERO key to release the held pressure value then depressurize, Electronic contact on
Pressure Switch will reverse and locked up the display value.
Pressure Switch Hysteresis value is difference between when pressurize then electronic contact
changed and when depressurize then electronic contact changed.
