1. Safety Precautions
This product complies with the requirements of the following European Community Directives:
2004/108/EC (Electromagnetic Compatibility).
To ensure safe operation of the equipment and eliminate the danger of serious injury due to shortcircuits (arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from any legal
claims whatever.
* Do not use this instrument near high-energy circuits.
* Do not operate the equipment near strong magnetic fields (motors, transformers etc.).
* Do not place the equipment on damp or wet surfaces.
* Do not place water-filled containers on the equipment (danger of short-circuit in case of
knockover of the container)
* Do not operate the meter before the cabinet has been fully closed.
* Comply with the warning labels and other info on the equipment.
* The measurement instrument is not to be to operated unattended.
* Always start with the highest measuring range when measuring unknown values.
* Do not subject the equipment to direct sunlight or extreme temperatures, humidity or
dampness.
* Do not subject the equipment to shocks or strong vibrations.
* Keep hot soldering irons or guns away from the equipment.
* Allow the equipment to stabilize at room temperature before taking up measurement (important
for exact measurements).
* Replace the battery as soon as the battery indicator appears. With a low battery, the meter
might produce false reading.
* Fetch out the battery when the meter will not be used for long period.
* Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or
solvents.
* The meter is suitable for indoor use only
* Do not store the meter in a place of explosive, inflammable substances.
* Do not modify the equipment in any way
* Do not place the equipment face-down on any table or work bench to prevent damaging the
controls at the front.
* Opening the equipment and service – and repair work must only be performed by qualified
service personnel
* Measuring instruments don’t belong to children hands.
1.1 Cleaning the cabinet
Clean only with a damp, soft cloth and a commercially available mild household cleanser. Ensure
that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

5. Auto Power Off Mode
The meter enters sleep mode (default). That is to say, the meter will automatically shut off after
20 minutes if no button press occurs for 20 minutes.
6. Operation
6.1. Measuring Pressure
The Primary Display number is Pressure value, the device measures Gauge/Differential Pressure, it
features 11 selectable units of measure: PSI, mbar, hPa, inH2O, mmHg, ozin2, ftH2O, cmH2O,
kgcm2, bar
1. Press the “UNITS-button” to enter the pressure mode and press the “UNITS-button” to select
unit.
2. Connect a single hose to the "Input (+)" port, leaving the "Ref (-)" port unconnected.

P/V/F
3. With the tubing open to ambient conditions press the “HOLD-button” and hold for 2 seconds to
zero out the display.
4. Place the input hose in a different zone than the Meter.
5. The Meter displays the differential pressure of the input zone with respect to the reference
zone.
-15-
For instance, a positive reading means that the input zone is positively pressured with respect
to the Meter location or its reference zone.
6.2. Holding the Displayed Readings
1. Press the “HOLD-button” to freeze the readings on the display .The display shows HOLD.
2. Press the “HOLD-button” again to turn off the HOLD function
6.3. Viewing the MIN, MAX, and AVG Readings
1. Press the “REC-button” to step through the maximum (MAX), minimum (MIN), or the average
(AVG) readings. The elapsed time since entering MAX/MIN/AVG mode, or the time at which the
minimum or maximum occurred appears on the display.
2. Press the “REC-button” for 2 seconds to exit MAX/MIN/AVG mode.

8. Error Codes
An error message will appear on the display if the meter fails an internal diagnostic test. And it will
freeze all the buttons.
Err. 1: Pressure value is over the range.
Err 2.: Pressure value is below the range.
Err 3.: DIF function, the differential pressure value is over range.
Err 4.: DIF function, the differential pressure value is below range.
9. Replacing the Battery
When the entire display shows the low battery indication, the 9 V battery has fallen to a critically low
voltage level and should be replaced as soon as possible.
1. Take off the battery cover at the button side of the instrument,
2. Remove the old battery and replace the new 9 V battery.
3. Make sure that the battery is installed to the right position and connected to the proper
polarisation with the battery snap.
4. Put on the battery cover and let it snap in to secure.

Statutory Notification about the Battery Regulations
The delivery of many devices includes batteries, which for example serve to operate the remote
control. There also could be batteries or accumulators built into the device itself. In connection with
the sale of these batteries or accumulators, we are obliged under the Battery Regulations to notify
our customers of the following:
Please dispose of old batteries at a council collection point or return them to a local shop at no cost.
The disposal in domestic refuse is strictly forbidden according to the Battery Regulations. You can
return used batteries obtained from us at no charge at the address on the last side in this manual or
by posting with sufficient stamps.
You can obtain further information about the Battery Regulations from the Bundesministerium für
Umwelt, Naturschutz und Reaktorsicherheit (Federal Ministry of Environment, Nature Conservation
and Reactor Safety).
This manual considers the latest technical knowing. Technical changings which are in the interest
of progress reserved.
We herewith confirm, that the units are calibrated by the factory according to the specifications as
per the technical specifications. We recommend to calibrate the unit again, after 1 year.

Batteries, which contain harmful substances, are marked with the symbol of a
crossed-out waste bin, similar to the illustration shown left. Under the waste bin
symbol is the chemical symbol for the harmful substance, e.g. „Cd“ for cadmium,
„Pb“ stands for lead and „Hg“ for mercury.
