How do I compesate for not having a kiln sitter dial for setting elements to low, med, high? I candle for an hour then ramp times for sitter switches on/off to temp for bisquing /firing. Many times I over fire. Using a thermometer/thermocouple to know that I've gone to temp. Ramping takes the whole day. Most efficient kiln sitter usage ideas appreciated. TY.
