Alarm Setup
User can choose setting of relays here;
The user can set the relay ‘High alarm’ or ‘Low alarm’ through the ‘Alarm mode’ of the relay. The default of relay 1 is ‘High alarm’, and the
default of relay 2 is ‘Low alarm’ When value is beyond the high/low limit, a ticking sound will be emitted.
Eg.: When the PH value exceeds 10.00, an alarm is required. Enter 10.00 in the limit value setting. After the setting is completed, the
instrument will make a ticking sound after the PH value exceeds 10.00, At this time, in the measurement mode, ‘High Alarm’ will be
displayed in the lower left corner. At this time, the normally open end of the relay is closed, and the normally closed end is disconnected,
and the relay starts to work.;
Current Setup
The user can set the output current here;
Can choose ‘Main test’ or ‘Temp’
There are three types of ‘output type’ to choose from, namely ‘4~20mA’, ‘20~4mA’ and ‘0~20mA’, which correspond to the upper and lower
limits of the measured value respectively;
Take pH as example, Choose ‘Main value’ , ‘4-20m’ as output, upper limit (PH) is 14, lower limit(PH) is 0, then 4mA means that PH is 0.00,
20mA means that PH is 14.00.
