[. . . ] 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 · 9-pin sub D-connector (male) · 6 pin 5 mm screw-terminal bus (female) 1 __________________________________________________________________________ U370EN-1. 1 USER'S GUIDE___________________________________________________________________________ OPERATION Remove the PTB220TS from the package and connect a wall adapter to recharge the battery. 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. FIGURE 1 Back plate of the PTB220TS tilting frame U370EN-1. 1___________________________________________________________________________2 OPERATION_____________________________________________________________________________ Tilting frame The barometer is mounted in a separate wooden case, tilting frame. It can be set to three different positions: horizontal, ~20° and ~40°. For a tabletop use, the tilting frame can be removed from the case by lifting upwards. NOTE The pressure connector has to be removed before closing the wooden carrying case. Battery The battery gives a twelve-hour service period. The period is even longer if the back light is not used. Recharging lasts about 12 hours and is therefore typically done overnight. Manufacturer: Type: YUASA NP 0. 8-12 NOTE To prolong the battery lifetime it is recommended to recharge the battery when not in use. RS232 The pin assignment of the RS232 serial interface D-connector of the PTB220TS/CASE is as following: 5 43 21 9876 VAISALA ______________________________________________________________________________3 USER'S GUIDE___________________________________________________________________________ PIN 1 2 3 4 5 6 7 8 9 SIGNAL not used TX RX not used ground for RS 232 not used not used not used not used RS485 The pin assignment of the RS485 serial interface connector of the PTB220TS/CASE is as following: PIN 1 2 3 4 5 6 SIGNAL not used RS485 HI not used not used RS485 LO not used LED Indicators There are four LED indicators in the back plate of the tilting frame. The LED indicators inform the user of operating status of the barometer. The green PWR led indicates that the PTB220 barometer is switched ON. The red BATT led indicates that the internal lead battery is being recharged. When the battery is fully charged the led returns dark. [. . . ] Place the conducting wire end to left-hand side. Fix the support bar of the pressure port to the spacers. Connect the flat cable and the battery conducting wires to the electronics board. Fasten the back plate by using the M3x18 spacers and M3x5 screws. [. . . ]
