It is important to know that this adjust offset value is only saved in the valve. You have to enter it again, if you change the valve. But as long as you use the same valve, you can switch off the control unit and the adjust offset value is kept. VTK-TR-BA-072e-1 - User Manual MDS 358X Series...
Operation 7.13 Dispensing with a Heater The Microdispensing System MDS 358X can optionally be equipped with a nozzle heater. One option is the MDH-48-BY (see Fig. 56). If a heater is connected to the system, the main menu shows the current temperature (in °C) instead of “Ready”. More detailed information about the menu, while using a heater, you can find in paragraph 7.13.1, page 77 and paragraph 4.5.3.2,...
You should calibrate the temperature settings of your heater in regular intervals. We recommend to do the calibration once a year. VERMES Microdispensing offers a calibrator set (Calibrator set for MFC 3000, order no. 1015434, see Fig. 58). The set contains two calibrators for different temperatures: Calibrator MFC3000 –...

(menu item “Cooler Offset”, see paragraph 7.14.2, page 81). The compressed air connectors of the VERMES flow control valves are marked on one side, “1” is “IN” and “F” is “out. These connectors have 6 mm diameter. If you want to connect the valve with a microdispensing valve with 3 mm connectors, you need a 6 mm to 3 mm adapter.
7.14.1, page 80). Press the [enter]-key and then use the arrow keys to set the desired value. A value of 0 % means that the cooler offset is deactivated. A value of 100 % would mean that the flow control valve is always opened completely. VTK-TR-BA-072e-1 - User Manual MDS 358X Series...
After working with self-curing substances, immediate cleaning is advisable in order to avoid clogging. This concerns the valve itself and all parts in contact with the fluid.
