4, Control point setting
4.1 Of VBWY-804 Thermoregulator:
The temperature control points of eachV BWS- 804 have been already set in accordance with JB/T6302-92
standard before its delivery. (refer to: 3. Main techuical parameters) If users need to change the value of set
points, please follow below procedures:
4.1. 1 take off the meter cover with a supplied 10mm solid wrench;
4.1. 2 Unscrew switch fixed bolts with a supplied 6mm solid wrench (refer to figure 4 );
4.1. 3 stir the red setting needles to set value planned;
4.1. 4 screw back switch fixed bolts;
4.1.5 close the cover.
4.2 Of VXMT-288F/288FC digital display thermometer:
4.2. 1 shift the toggle switch to "set" position(Figure 3 );
4.2. 2 Adjust the regulating potentiometer until the temperature value planned;
4.2. 3 shift the toggle switch back to "measurement" position.
