PRODUCT DESCRIPTION
The PTB220TS and a PTB220AxB2Ax barometer (order specified) are
assembled together at factory to become a Transfer/travelling standard.
It is also possible to assemble the customer's existing PTB220
barometer and separately ordered wooden case (PTB220CASE); see the
instructions on page 5. Please note, that there are certain requirements
for the PTB220 barometer to be compatible with the case. The
barometer should have the following features:
−1, 2 or 3 pressure transducers
−class A accuracy
−local display
−RS232/485 serial interface
This guide gives the basic operating instructions of the PTB220TS. It
does not, however, replace the operating manual of the PTB220 series
digital barometers. For detailed operation instructions and descriptions
refer to the User's Guide of the PTB220.
The PTB220TS includes the following parts
•a wooden (oak) carrying case
•wide and comfortable carrying handle
•two key locks
•a space reserved for small parts and documents in the case lid
•tilting frame where the barometer is mounted for table-top use
•incorporated sealed lead acid battery (YUASA NP0.8-12)
•power cord for recharging from car cigarette lighter socket
•DC plug for a local mains adaptor cord
•pressure connectors: for 1/8" tubing and a 5 mm connector

OPERATION
Remove the PTB220TS from the package and connect a wall adapter to
recharge the battery. Switch the power on. The barometer is now ready
for use. For detailed operation instructions and descriptions refer to the
User's Guide of the PTB220 series digital barometers.
NOTE The pressure port is closed, if the pressure connector is detached. For
measurement, the connector MUST be on place.
Operating voltage
DC voltage of 10...25 VDC is required to operate the barometer. A
power cord with a suitable plug-in connector is supplied with the
PTB220TS for use with a local power source. It is very important to
observe the polarity of the DC supply voltage.
NOTE Negative terminal is in the center.
If the wall adapter is used, the barometer will operate from the mains
and at the same time recharge the internal lead battery of the
PTB220TS. If no adapter is used the PTB220 barometer will operate
using the internal lead battery.
