Switch the Pressure Measuring Adapter to the appropriate desired
units of measurement (metric, kPa; or British/American, psi) and set
the connected Voltmeter to the 200mV DC measuring range.
If the Voltmeter indicates a voltage on a pressure-free System, then
setting "ZERO" must be carried out.
If the Voltmeter is overloaded while measuring pressure (usually in-
dicated by "OL" for "Overload"), then set the Voltmeter to the next-
B Negative pressure (vacuum) measurement
The maximum-permitted vacuum input level must
not be exceeded under any circumstances.
. . . . < 1
Connect no voltages to the Pressure Measuring Ad-
apter; it tan be destroyed by this.
Switch the Pressure Measuring Adapter to the appropriate desired
units of measurement (metric, cmHg; or British/American, inHg)
and set the connected Voltmeter to the 200mV DC measuring ran-
ge. If the Voltmeter indicates a voltage on a pressure-free System,
then setting "ZERO" must be carried out.
Disposal
If the Pressure Measuring Adapter does not function in spite of
good supply (9V battery) or is no longer repairable (fracture in the
measuring transducer or threaded connection), then it must be dis-
posed of in accordance with applicable statutory regulations.
