Parameter specification
Parameters are classified as six groups according to their functions. Parameter is not displayed on the surface if there is no related function.
Group 1 Alarm setting
AH set value of first alarm
AL set value of second alarm
Group 2 Code and alarm state
OA code
It should be set as “1111”, parameters in other groups can be modified.
oA is set as “0000” when the instrument is powered on or no key is pressed in a connective minute

Alo2 alarm pattern for second alarm
--1H alarming when the measuring value is more than the set value of alarm for the first channel
--1L alarming when the measuring value is less than the set value of alarm for the first channel
--2H alarming when the measuring value is more than the set value of alarm for the second channel
--2L alarming when the measuring value is less than the set value of alarm for the second channel
1-2H alarming when the value of the measurement of channel one minus the measurement of channel two is more than the set value of alarm
1-2L alarming when the value of the measurement of channel one minus the measurement of channel two is less than the set value of alarm
