2. Switch on the power, turn it on, the indicating light is on, which means it works in
normal. The meter will display the temperature of workroom, then regulate the control
meter to the setting temperature, poen the heating switch, the workroom begins to
heat, the green light on the control meter is on, which means it is power on and
temperature is rising. After 60 minutes, constant temperature of instrument, the
display temperature should be in conformity with the setting temperature.

3. If you required lower temperature, for emample 60°C,you could adopt second
setting style, set 50°C at the first time, when the overshoot temperature fall after rise,
set 60°C at the second time, in this way, you could reduce or stop the overshoot
temperature.

lower than 50°C,the value measured by standard thermometer is different with the
display value of meter, that is normal. It could not affect the temperature contro! and

precision when the temperature is higher than 50°C.
