5. INTRODUCTION The ALMEMO ® 2790 series is a new member in our family of unique measuring devices - all equipped with Ahlborn's patented ALMEMO ® plug system. These systems incorporate a wireless Bluetooth module and, via the Bluetooth sensor... -
Page 10: Sensor Programming
5. Introduction 5.1.1 Sensor programming The measuring channels are programmed, completely and automatically, via the ALMEMO plugs; they are ready-to-operate immediately. However, via in- ® terface cable ZA1919-DKUx the user can still add to or modify the program- ming. (see Man. 6.3) Or, alternatively, the sensors can be programmed on the ALMEMO ®... -
Page 11: Putting Into Service
Putting into service 6. PUTTING INTO SERVICE 1. Plug wireless sensor module ZA1729-BTFS into a sensor socket on the ALMEMO ® measuring instrument or data logger and switch the device ON. 2. Connect the sensor at socket M0 (1) on the 2790 device see 9. 3. -
Page 12: Operation Using Standard Batteries
7. Power supply current consumption of 8 mA is approx. 230 hours. In sleep mode with a cycle of 1 minute it should be possible per battery charge to perform measuring ope- rations for approx. 390 hours. By extending this cycle to e.g. 1 hour, this time can be increased to approx. -
Page 13: External Dc Voltage Supply
External DC voltage supply 7.3 External DC voltage supply The DC socket (3) can also be used to connect another DC voltage, 6 to 30 V (minimum 200 mA). It can be connected using ALMEMO ® plug ZA1000-FSV. If, however, the power supply has to be electrically isolated from the transducers, then electrically isolated supply cable ZA 2690-UK must be used. -

Measuring inputs und additional channels With option RHA the measuring instrument also incorporates a digital sensor for temperature, humidity, and atmospheric pressure (2), occupying channels M01 to M31. However, in wireless transmission to a subsequent linked device, only four channels can be transmitted, normally the first four (M00 to M30 or M00 to M11). -
