Operating Instructions:
1. Turn the DigiMano 1000 ON and allow two minutes for the transducer to warm up
and stabilize.
2. Select the desired engineering unit to be displayed.
3. With no pressure applied the display should read zero (0). If not, adjust the
manual zero adjustment potentiometer.
4. Connect the DigiMano 1000 to the device to be tested or to a pressure vacuum
line.
5. Read the pressure or vacuum in the measurement units that have been selected
by the Unit Selector Switch. The negative sign (-) will be displayed when reading
vacuum measurements.
Precautions
1. Do not exceed the rated maximum pressure of the instrument, although a
transient pressure of two times the rating will generally be tolerated.
2. Do not connect the instrument to corrosive gases or highly ionic fluids.
3.
Do not continue to use if the instrument is wet.
Trouble Shooting
When inaccurate pressure vacuum readings are suspected, check the following items:
1. Install a fresh 9 Volt battery.
2. Turn the DigiMano 1000 on and verify that the display reads zero with no
pressure applied to the instrument, 00+/- 1 count.
3. Adjust the zero adjustment potentiometer as necessary.
4. Connect the instrument to a pressure source, apply a known pressure, and verify
the reading within the specifications of the DigiMano 1000 model, 0.25%+/- 1
count.
