1 Introduction
The SPG-DIGI is a digital manometer featuring a MIN/MAX display function. Full scale (FS) accuracy is
± 0,5% based on the upper limit of the measurement range.
Dynamic pressure peaks are measured at a scanning rate of 10 ms (100 measurement values/second).
The MIN/MAX memory is continuously updated and rewritten.
1.1 Notes on Safety / Product Selection
The correct functioning of the SPG-DIGI can only be guaranteed when the specifications detailed in
these operation instructions are adhered to. In particular, specifications relating to the permitted upper
limit of the measurement range as well as the permissible temperature range must be observed.
Serious malfunctions leading to personal injury or damage to property can result from using the
chosen product in applications that do not comply with the specifications or from disregarding the
operation instructions. In particular, incorrect mounting of the manometer and the corresponding adapter
can cause the manometer to be torn out of the assembly.
For Service, Repair and Calibration of the measurement instruments please contact your STAUFF
sales branch.

2 Commissioning
The SPG-DIGI is supplied with batteries fitted.
The device is operational as soon as it is turned on.
Caution!
Turn off the device before replacing the
batteries. Open the battery compartment.
Insert the new batteries as depicted. Ensure
correct polarity of the batteries.
Batteries: 2 x 1,5 V (LR6 - AA)
2.1 Replacing the Batteries
When in continuous operation (without light), the service life of the batteries is 1.500 hours.
A battery symbol permanently displays the actual battery status.
The serial number is of the SPG-DIGI pressure
gauge is no longer displayed on a label under the
protective rubber cap but now in the SPG-DIGI
software menu.
Please press the button
MENU
ZERO and hold the button
for min. 2 s. The SPG-DIGI will switch through the
following menu points on every keystroke:

4 Connection to the Hydraulics
The SPG-DIGI is available with male thread G ¼ (BSPP) or 7/16-UNF for the corresponding versions
(bar / psi). Several adapters for other pressure connections can be supplied also.
Please make sure that the device is properly mounted to avoid malfunctions.
Please do not assemble while the SPG-DIGI is pressurized
Connection Designation Adapter
G1/4 to M16x2 SDA20-G1/4

Use this key to toggle the required value.
The key function is sequential; the values are indicated in the display in sequence.
The MIN/MAX function is used to measure pressure peaks. The respective lowest (MIN) and highest
(MAX) measured values are stored in the MIN/MAX memory. Values in the MIN/MAX memory are
erased when the device is turned off. If different pressure tests are to be carried out in succession, the
MIN/MAX memory must be erased after each measurement.

range (at appr. 20% overload from FS).
If the message will remain displayed, while the SPG-DIGI is
pressure less, please consult your local STAUFF office.

5.8 Zero Point Correction (ZERO)
The zero point can be corrected manually should undesired deviations occur when no system pressure
is being applied (atmospheric pressure).
ON
OFF
Caution! The zero point correction sets the current ACT value to zero.
In order exclude erroneous measurements; ensure no system pressure is
being applied when carrying out this function.
Press ZERO (quick)
MENU
ZERO
RESET
OK
This initiates the zero point correction..
The ACT (actual) value is indicated in the display as 0.0 bar.
This correction remains active until the device is turned off.
OFL / ZEro is displayed for 3 s if the measured pressure is
greater than 5% of the measurement range.
Zero point correction cannot be carried out.
Please ensure that no system pressure is being applied.
5.9 Resetting Zero Point Correction
Turn off the device.
Zero point correction is no longer active when the device is turned off and on again.
