8.5 ORP calibration:
It is unnecessary to make regular calibration for ORP electrode as pH electrode,
and it is only necessary to use ORP Buffer to check the electrode or adjust the
deviation of electrical potential. Push for the adjustment of ORP
zero-point electrical potential.
1. Clean the electrode completely, and put it into the
buffer solution. Check the difference between the
readout and buffer solution. Push or to
set the digit until it is equal to the buffer’s standard.
Then, push to ensure it and push to
back to the measurement mode.
9. Instruction set for RS-485 (PC-3100RS only)
RS-485 should apply MASTER+ SLAVE structure, which means that MASTER
(computer) sends out orders and SLAVE (controller) is responsible to respond to the
order. A standard RS-485 network totally contains 32 points of MASTER and SLAVE.
Usually, MASTER=0 and SLAVE=1~31. Every RS-485 equipment has a specific ID
which helps to identify whom the order is sent to, so please set up the ID in the set-up
mode.
Factory default:
ID=031
Baud Speed=9600
