Set the test data return to ON,
Command message: FETCh：AUTO ON or FETCh：AUTO 1
--Return message
Query message: FETCh?
The current measurement result will be returned.
Command syntax: FETCH?
When the instrument receives the command, it will automatically return the measurement result until the
end of the test.
Return format:
Step：Test item：Test voltage (V), Test current (mA), BIN result;
⑴ ⑴ ⑵ ⑵ ⑶
(1): Steps and test items, the separator between test items and data is (:).
(2): The delimiter between test data is (,). The separator between different unit data is (;)
(3): The separator between steps is (; + space). The end of data defaults to (0x0A).
Note:
1. All data is an integer or floating-point format, ASCII string.
2. The data unit is the same as the FUNC set commands by default. No unit is returned when the string is
returned.
The test results are:
STEP1: AC: 1000V, test current is 1mA, result PASS.
STEP2: IR: 500V, test resistance 100M, result PASS.
Return data format:
STEP1: AC: 1000, 1.000, PASS; (SPACE)
STEP2: IR: 500,100.000, PASS; (0x0A)
5.7 Other Commands
*IDN Inquiry about the model and version information of the instrument
Return message: <manufacturer>,<model>,<firmware><NL^END>
Where,
<manufacturer> Gets the manufacturer name (Tonghui)
<model> Gets the machine model (such as TH9320/9310)
<firmware> Gets the version number of firmware (such as Version1.0.0)
For example: WrtCmd(“*IDN?”);
5.8 Command debugging sequence
1. Make sure the communication hardware is RS232, RS485, USB, GPIB.
2. Install the corresponding communication driver or debugging software. Make sure the setup
parameter of computer matches with the parameter in instrument.
3. Use (*IDN?) to confirm that the communication is connected and that normal text can be transferred
in both directions.
