| -70℃~+150℃ |
| Temperature:±0.2℃ (The difference between the controller setpoint and actual value of the controller) |
| ≤0.5℃(Temperature fluctuation is half the difference between the center of the highest measured temperature and the minimum temperature.) |
| ≤±1℃(The average temperature of the studio temperature controller displays the value to minus the average temperature measured of the center) |
| ≤2.0℃(Temperature uniformity is each difference in the measured maximum and minimum temperatures of the test of arithmetic mean.) |
| 3℃/min(Nonlinear load) |
| 0.75~1.2℃/min(Nonlinear load) |
4.11 Working noise | A Sound Level≤70dB(A) (At ambient temperature 25 ℃ and measured in the room of echo less interior noise; Using A-weighted, average of eight test points; Each test point level from the noise source 1 m, the height from the ground 1 meter.) |
