set factor will be multiplied by the PSI measured, the result will be
displayed.
For example: 40 PSI is the equivalent of 1000 lbs of product in a
tank. You want to display the product weight , using a 100 PSI
gauge. By setting a factor of 25, a 40 PSI pressure would display
as 1000 (40 x 25). The engineering unit displayed on the
DPG4000 will be “Cust”.
Normal Operation
Turning the backlight on and off
: Press the ENTER button.
Zeroing the display
: Press and hold the ZERO button.
MAX/MIN
: The DPG4000 stores minimum and maximum pressure
values in memory. Pressing the MAX/MIN button once will display the
minimum pressure from memory. Pressing the MAX/MIN button again
will display the maximum pressure from memory. After about 2
seconds, the gauge returns to normal (live display) operation. To clear
the MAX/MIN memory registers, press and hold the MAX/MIN button
for 2 or more seconds until “CLr” is displayed.
The analog bar graph at the bottom of the display indicates the applied
pressure level relative to the full range of the gauge. Keep in mind that
if a TARE value has been programmed into the gauge, the displayed
pressure will not reflect the true pressure applied.
Changing the Batteries
WARNING
Explosion hazard
Batteries must only be changed in an area known
to be non-hazardous.
Grasp the face ring on the DPG4000, turn it approximately ¼ turn
counterclockwise and remove. The face of the gauge can now be
lifted to expose the battery holder. Take off the battery hold clip and
remove the batteries. Install three AA batteries noting proper polarity.
Note: Use
ONLY
AA size batteries and be sure to reinstall the battery
holder retaining clip. Reassemble the case making certain that the face
is properly oriented.
If you purchased the optional 24 Volt powered version, the terminals for
power input are located on the rear of the gauge. To apply power
simply connect 24 volts to the rear terminal block taking care to
observe proper polarity.
