    Tip 5 ► It is particularly indicated to use a low heating rate in case of Objective Heater acting on a very sensitive objective. Check with the objective manufacturer. Tip 6 ►The ramp rate can be defined in the range 0.1-1.5°C/min. Above 1.5°C H401-T-CONTROLLER attributes the value MAX to the ramp rate.

  • Page 20: Calibration Routines

    To perform the calibration it is necessary to measure the temperature of the liquid inside the sample holder. For this reason, the H401-T-CONTROLLER is equipped with a fine gauge temperature sensor, which can be immersed in water and oil (see pointer 2 of Figure 1).
  • Page 21 To start the calibration procedure, follow these instructions: Make sure the T Sensor is connected to the H401-T-CONTROLLER (see Figure 4 and pointer 5 of Figure 3). Secure with commercial adhesive tape the T Sensor to the bottom of the sample holder you use during standard operation (Petri dish, Chambered Glass Slide, etc.) as shown in Figure 22.
