6.7 Key lock
To avoid accidental changing of the set values, push the MAIN button in the menu
item ”set temperature”.
In this menu item can you see the actually temperature in the SV-line and the remaining
time of turn-off delay in the PV-line. The function of the Jog-Dial knob is deactivated.
Press the MAIN button once more to leave the key lock. Than you are in the menu item
“set turn-off delay”.
6.8 Storage function
The
Refrigerated Bath Circulator
includes a storage function for temperature and time values.
That is practical if you want to work with the same parameters often. Then you didn’t need to set
them in every usage.
For storing values you only need to hold the Jog-Dial knob pushed for two seconds.
Successful storing is displayed by blinking of the SV for three times.
Any stored parameters are erasable. Turn the value with the Jug-Dial
till “0” and then
hold the knob pressed for two seconds.
If you want to overwrite a value it is not necessary to erase the old one. Set the desired
value and use the Jog-Dial knob for storing.
