The BBC Goertz Metrawatt M2110 is a historic (about 1984) 30000 count bench multimeter with RS232 connectivity.
A multimeter called Metravo 5D from the same manufacturer that seems to be the same model without RS232 port received the "iF design awards" in 1981.
The manufacturer is called Gossen Metrawatt today.
Hardware
RS232 Interface:
- Baud rates 150/300/600/1200/2400/4800/9600, configurable via rotary switch
- 7 data bits
- No/even/odd parity bit, configurable via DIP switches
- 1 or 2 stop bits, configurable via DIP switch
- Optional CTS handshake, configurable via DIP switch
- Output intervals 0,66s/10s/1m/10m/1h/manual/remote controlled, configurable via rotary switch
- Manual output sends value on button Start/Reset pressed.
- Remote controlled output sends data on CTS set or ENQ sent, configurable via DIP switches
- Max. 1,5 measurements/s.
RS232 cable:
- 25 pin "female" connector
- Null modem cable required (DTE configuration)!
