GOSSEN METRAWATT GMBH 19
7.7 Set Transmission Speed – bAud-ou, bAud-in
• Set Transmission Speed to the PC – bAud-ou
Key Sequence: SEt ... ... bAud-ou 19200
Settings: 9600 (default setting), 19,200 or 38,400 baud
This parameter sets the speed of data transmission between the memory adapter and the
PC. The same baud rate must be selected in METRAwin 10 software at the PC.
• Set Transmission Speed to the Multimeter – bAud-in
Key Sequence: SEt ... ... bAud-in 9600
Settings: 9600 (default setting) or 8192 baud
This parameter sets the speed of data transmission between the memory adapter and the
multimeter.
Note: 8192 baud is the only transmission speed available with METRAHit 1xS multimeters.
METRAHit 2x series multimeters automatically transmit at a speed of 8192 baud if the
RS232 or the SI232 setting has been selected. The SI232-II must also be set to 8192 baud
in this case.
If you want to operate the METRAHit 2x at 9600 baud it must be set to adapter type BD232
(under interface parameters), and the SI232-II must be set to 9600 baud.
7.8 Start / Interrupt / Stop Data Recording – StorE, LAbEL
• Start Data Recording (StorE mode)
Preparations at the multimeter:
– Select the correct adapter type as follows:
SI232-II: AdAPt = SI232 onlinE
SI232: AdAPt = SI232 StorE
(DMM menu: SEt ... ... SI232 StorE ...)
– Select a sampling rate, e.g. ratE = 0.05. METRAHit 12S-18S instruments cannot be
adjusted: A fixed baud rate is used which is dependent upon the measuring function.
– Select the required measuring function (V, A, ...), as well as the measuring range.
– Activate measurement data transmission by simultaneously pressing DATA and ON,
or in the menu: SEt – SEnd – on.
Preparations at the adapter:
– Data recording is influenced by the following settings, which should therefore be checked
in advance: sampling rate (rAtE), hysteresis (HYSt), trigger settings (triG), recording dura-
tion (durA), recording type (CYCLE).
– Weekday and time (tiME) should be properly set.
If the contents of the adapter’s memory are to be read out subsequently along with other
adapters, the adapters’ clocks should be set with the help of METRAwin 10 to assure
correct synchronization.
➭ Select manual data recording with the SEt and rAtE functions. The following display must
appear: –:– –.– –
➭ After the adapter has been switched ion, press ESC and ON simultaneously. Memory
occupancy is displayed as a percentage, for example 00.0 if the memory contains no
data. DATA and ON appear briefly at the display.
