Product catalog summary

Overview: This document provides technical specifications and instructions for the Ministat, Ambistat, and Galvanostat devices, covering all versions. It includes details on switching differences, sensor and protection tube mounting, electrical connections, and adjustable differentials.

Switching Difference (Hysteresis): The switching difference can be adjusted using a knurled knob on the operating lever. Turning the knob to the left increases the differential, while turning it to the right decreases it. Precise adjustments should be made using a thermometer during operation.

Mounting of Sensor and Protection Tube: When filling the protection tube with silicone oil to improve heat transfer, ensure that the oil can expand to prevent damage.

Electrical Connections: The document specifies the terminal connections for phase entry and exit for heating and cooling. It also provides electrical ratings for various switches, indicating the voltage and current capacities for both AC and DC.

Adjustable Differential: The differential is adjusted using a knurled cap with a marking scale. Adjustments should be made with a thermometer to ensure accuracy, and the upper switching point remains steady during adjustments.

Temperature Ranges: The document lists the operating, sensor, and storage temperature ranges for various models, emphasizing that the sensor temperature should not exceed its maximum limit.

Important Notes: The scales provided are for setting assistance and may have slight deviations from actual values. For precise settings, a thermometer should be used. In case of large deviations, readjustment is necessary.
