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

ZERO and hold the button

for min. 2 s. The SPG-DIGI will switch through the

following menu points on every keystroke:

- Automatic Switch off (PO, 5.10)

5.4 MIN/MAX Display

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.

5.7 OFL Display

This indicates that the applied pressure is outside given full scale

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).

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)

ZERO

RESET

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.
