Got to figure out the method of calibrating my brand new hotplate-magnetic stirrer to the required temperature.
Its a bit different from many hotplates because it has quite a few additional features. Such as rather than have to climb slowly from room temperature to whatever the set temperature desired might be, its got the ability to ramp up the temperature at a rapid rate, as calibrated by the user and stop at a set breakpoint before the desired temperature so it heats up the plate surface itself very, very rapidly until the inbuilt thermocouple probe inserted into whatever one wishes to heat and/or stir reads that the actual thing to be heated has reached the breakpoint, which one sets a few degrees below the actual temperature, so that the temperature rockets up to whatever is desired within a minute or two, then cuts out and starts heating slowly at a breakpoint you set a few degrees or whatever you want, below the actual intended end temperature, again set by the user (as well as a facility for two timers, one to set total heating time and then cut the heat out completely, so you can just set it and go to sleep if you know whatever you are doing cannot suddenly start getting violent and doesn't need a conscious, attentive babysitter. If it just sits there and has to get hot you can set it to do just that then stop when it's done automatically. As well as an alarm settable so if it exceeds the temperature the alarm is set at it goes off to warn the user of the hotplate-stirrer.
Unfortunately the instructions are in chinese, translated to the most absofuckinglutely godsawful engrish, I think, by way of german in the middle and are barely comprehensible. And I had to go online to find a set of similarly awful mangled engrish language, bastardized to hell and back again, that had a complete set of instructions, since the one that came didn't even mention the timer or alarm.
I need to calibrate this bastard so it stays stable and actually stays at the temp. set to, without having to program it to try and stay hotter or colder than it actually needs to be. And the so called manual states various things as being both correct procedure AND an error.
And rather than plain simple setting the breakpoint there is math involving division, and you have to work out what to divide what by before doing it. And I'm really severely dyscalculic and can't understand even the example given in a way that enables me to apply it to other figures, for the temperature ramping and stability/error calibration.
