II. Quick Start for DRPG-531
While this vacuum instrument has many features, it is very simple to use. First, unpack the gauge to
be sure that you have received everything that you ordered.
Next:
1. Remove protective hood
2. Remove the battery cover and install 4 AA batteries.
3. Plumb the thermocouple sensor into the system to be measured, taking care to keep the
stem down.
4. Power on the device by pressing the ‘PWR’ button. It will take about 5 seconds to turn
on.
5. If need be, turn on the backlight. The backlight does not affect gauge reading or
accuracy.
6. Read vacuum!

III. Modes of Display
The DRPG-531 has four modes of display: one numeric and three graphs. The numeric display has
three numeric formats: Standard, Precision and Scientific. Display modes are selected from the
Configuration option ‘Display’ and Numeric formats are selected from the Configuration option
‘Numeric’. The SEL button enters and traverses the Configuration menu.
A. Display Numeric
The following example shows the numeric display with the ‘Precision’ format:
The following image shows the numeric display with the ‘Scientific’ format
The Numeric display shows the currently configured units, in these examples, the vacuum pressure
units are ‘microns’ or ‘Torr’. Below the units indicator are the battery, vacuum pressure, and vacuum
system analysis indicators.
In any display mode, the UP and DOWN buttons turn the backlight on and off (respectively). The
SEL button enters the configuration MENU, and the ENT button turns the gauge on or off.
