Scope of supply
The scope of supply includes:
- Device, incl. 9V battery block
- Operation manual
Operation and maintenance advice
Battery operation:
If the symbol “BAT“ is displayed on the left side of the display, the battery
is weak, measuring can be continued for a certain time. If “bAt“ is displayed
in the main display the battery is used up and needs to be replaced. Measuring
is no longer possible. The battery has to be taken out when storing the device
above 50 °C. We recommend taking out the battery if the device is not used for
a longer period.
Configuration of the Device
To configure the instrument proceed like follows:
-
Switch off the instrument.
-
Press the ‘Mode‘ key while switching on the instrument, and keep the ‘Mode‘ key pressed until ‘P.oF‘ appears (after about 3 seconds).
-
Auto Power Off Time „P.oF“ The auto power off time is entered in minutes. If no key is pressed during measuring, the instrument switches itself off automatically after the entered period.
-
Press the up‘ or ‘down‘ key, and the currently selected power-off time will be displayed (off, 1..120min)
-
Enter the desired time by pressing the ‘up‘ or ‘down‘ key. (factory setting: 20)
Possible input:
off 1…120: The auto power-off function is deactivated (permanent operation) auto power-off time in minutes. -
Confirm the value by pressing a left key, ‘Uni‘ appears in the display Display Unit „Uni“
-
Press the up‘ or ‘down‘ key, and the currently selected unit will be displayed: mbar = hPascal (‘hPA‘), mmHg (‘nHG‘), PSI (‘PSI‘) or Pascal (‘PA‘)
-
Enter the desired unit by pressing the ‘up‘ or ‘down‘ key. (factory setting: hPa)
-
Confirm the value by pressing the left key, ‘dyn‘ appears in the display
Measuring static/fast varying pressures “dyn“ (= dynamic) -
Press the‘ up‘ or ‘down‘ key, and the currently selected measuring mode will be displayed (see Chapter 5: “The Pressure Measuring”)
- dyn = off standard measuring of static pressures, optimum battery life
- dyn = on measuring of dynamic pressures
-
Enter the desired mode by pressing the ‘up‘ or ‘down‘ key. (factory setting: off)
-
Confirm with the left key: values will be stored, and the instrument will restart (segment test). End of configuration.
Please note: If during the configuration no key is pressed within 60 seconds, the configuration will be aborted. Eventually made changes won’t be stored!
The Pressure Measuring
The device measures the difference pressure between the two pressure ports:
(“+“ = higher pressure, “-“ = lower pressure) An automatic zero point
adjustment is performed when switching on the device! If a pressure is
connected when switching on, the high accuracy cannot be reached! As long as
no pressure is connected additionally the zero-point is automatically
stabilized. If a fast varying pressure should be measured (chimneys, etc.) the
“dyn“ measuring should be activated (see below). This function is filtering
the variations. Attention: “dyn“- measuring increases the power consumption
more than 10 times.
- Over pressure measuring: Connect to the “+“-port.
- Under pressure measuring: Connect to “the -“ port, under pressure ,will be displayed without a negative sign.
Notes to Special functions
- watch MIN value (Lo): press key ‘Mode‘ shortly once display changes between ‘Lo‘ and MIN value
- watch MAX value (Hi): press key ‘Mode‘ shortly once again display changes between ‘Hi‘ and MAX value
- restore current value: press key ‘Mode‘ shortly once again current value is displayed
- clear MIN-/MAX- value: press key ‘Mode‘ for 2 seconds MIN and MAX values are cleared. The display shows shortly ‘CLr‘.
Zero-Function
Using the zero-function, the display will be set to zero. This is mainly
intended to correct position dependency and drift of the sensor. Disconnect
both pressure ports before zeroing
- Press the “zero“-key for 2 seconds -> the display will be set to 0,
- Press “zero“ for 5 seconds -> Zero function will be reset.
- Relative measuring can also be performed by this function (= “tare“).
Scale Adjustment
The scale adjustment is intended to be used to compensate errors of the
internal pressure sensor. The display value is given by the following formula:
Display = measured value * ( 1 + scale adjustment/100)
To adjust a measuring scale proceed like follows:
- Switch off the device.
- Press the ‘Zero‘ key while switching on the instrument, and keep the ‘Zero‘ key pressed until ‘SCL‘ appears (after about 3 seconds).
- Press the‘ up‘ or ‘down‘ key, and the currently selected scale adjustment appears. (factory setting: off=0%)
- Choose the desired value by pressing ‘up‘ or ‘down‘ key. (max. input range: ±5.00%, off = 0%). The input is displayed in %.
- Example : scale adjustment is 1.00 scale is increased by 1.00% Scale = 101% At a measured value of 100 (without offset correction) the instrument would show 101
- Store the value by pressing the left key. The instrument will restart (segment test).
Please note : If during the changing of the scale adjustment, no key is pressed within 60 seconds, the input will be aborted. Eventually made changes won’t be stored!!
System messages
- Er. 1 = measuring range has been exceeded
- Er. 2 = meas. value has fallen below perm. range
- Er. 3 = display range has been exceeded (>1999)
- Er. 4 = meas. value has fallen below displayable range (<-1999)
- Er. 7 = System fault – the device has detected a system fault (defective or far outside the allowable ambient temperature range)
- – — = Sensor error or value could not be calculated
- „bAt “ = battery is used up => replace battery
