5.1 Electrical connections
Use only IEC 6 LR 61 batteries.
Open the battery compartment on the rear of the instrument by sliding off the
compartment cover. Plug the batteries in to the battery hook-up, making sure that the
battery terminals are properly aligned. Place the battery in the compartment and
replace the cover.
5.2 Pneumatic connections
Connect the EMA 200 to the pressure source at the overpressure port (+) when
measuring overpressure, at the vacuum port (-) for measuring vacuum pressure, or at
both ports (making certain to connect the + and - ports appropriately) for measuring
differential pressure.
6 Operating the instrument
The following sections explain how to operate the instrument correctly.
6.1 Switching the instrument on/off
Turn the instrument on or off by briefly depressing the
key. The
instrument displays its measurement range in mbar for roughly 1 s
immediately after it is switched on.
6.2 Display modes: measurement, hold, max., min.
The key allows the user to toggle between the various display modes
Pressing this key once will call up a different display mode. In hold, max and
min modes, users can begin a new measurement by briefly depressing the
zeroing key. In the display modes min and max, this will reset the
display value, because the actual value will be the new min or max value.
