After receiving of setting data from PC (U/V/W/
X/Y/Z), and will send out the receiving data again
then it is convenient for PC to check the accuracy
of data output are total 7 digits.
d. Command [BXXXXXX]:
Exit the SETUP mode
RS-232 Command Table
Use IR as the interface of Data transmission, and
use external computer to start RS-232 functions.
RS-232 Interface Parameter :
Baud rate : 1200
Parity check : EVEN
Data buts : 7
Stop bits : 1
(1) Setup Selections
a. Command S: Meter will enter the Setup mode
and return "SETUP READY..x".
(x:firmware version)
b. Command
[E(L/C/R)(Q/D/R)(P/S)(A/B)(A/M)(0~6)]:
Main function change
(L/C/R): L, C or R test function
(Q/D/R): Q, D or R
(P/S): P-PAL / S-SER
(A/B): A - 1KHz / B - 120Hz
(A/M): A - AUTO / M - MANUAL
(0~6): Manual range
c. Command [A-AAAAA]: Default change
(2) Read Data
Command N: Read Meter current data and
status.
Data format: There are 39 ASCII code.
The Main Display data just send L/C/R data
that don't process before (like the data before
REL).
The Second Display data is the same as Main.
