II.Operation method of running curve program
1. Three work state of the meter
State of stop:
When the meter is in the state of stop, the meter is used as the thermostatic control, the setting value is
the basic setting value(SP), display in the window below, the running indicator light turn off.
State of running:
When the meter is in the state of running, the meter constantly modify the setting value (SV)according to the setting curve, make the measured value(PV) changing according to the curve program, so as to achieve the purpose of curve program control, and the indicator light turn bright.
State of interim:
When the meter is in the state of interim, the calculagraph stop timing, the setting value(SV)maintain unchanged, and it also will prolong the running time of the curve program, the indicator light will coruscate.
State of automatic pause:
The state of automatic pause is the special form of the state of interim, created by the meter itself, not can be controlled by artifial. In the running state, when the deviation absolutevalue of themeasured value and present setting value(SV)>automatic pause strap (AL_P), the meter enter into the pause state, the indicator light will coruscate., the calculagraph stop timing, the setting value(SV)will not change. When the deviation absolutevalue of themeasured value and present setting value(SV)< automatic pause strap (AL_P), the meter will automatically resume the running state.
Hold state:
When the meter finish the curve program, and some section r=0, the meter will enter into the hold state (run=1), and the main control output closed, the indicator light turn off, the below window display the first setting value. When the outer switch touch off or set the meter Run parameter to 3, it can restart.
2. Disposal on the power-cut
During the running process of the curve program, the meter will for every 5 minutes to save the running parameter and the running state data, so when the power is off and then on, the meter only run according to the last saved data to continue,
Not from the beginning(if it need to start from beginning, press reposition key to start.

Connection(consult)
Note:Only one way for alarm use Alarm 1.only when alarm method ALP is (upper and lower limit alarm),
6(upper and lower deviation alarm) ,
(upper and upper limit alarm) ,10 (lower and lower limit alarm),it should use
Alarm 2,when upper and lower limit alarm or upper and lower deviation alarm,it should use Alarm 2 as lower limit or lower
deviation alarm.The indicator light will be lighten when the alarm output.
Note : when input current signal 0-10mAor 4-20mA ,it should respectively combine 1K or 250 250Ω
to input port.Change the current signal to voltage signal.
