 Don’t assume that your oven has stabilized at the preheat tone and start testing. Always
wait twenty minutes for an accurate reading.
 If time allows don’t make an adjustment to the ERC without first determining how it will effect
all three bake modes
 Don’t rush
The Do’s
 Take your time and get it right. It is better to stay a little longer than to come back.
 If your time is short, test the most accurate cycle (Pure Convection) and make an
adjustment based on that result.
 Always use a meter with at least two leads
 Always educate on the benefits of convection
 Wait at least twenty minutes prior to recording any cut in/cut out temperatures. High or low,
it will take the oven two or three complete cycles before it stabilizes
 Test as long as possible. Testing less than forty minutes will not give you a chance to record
enough rises.
Recommended Temperature Meter
Dacor recommends the relatively inexpensive Fluke 52 digital thermometer. This meter allows
the use of two thermocouples for better accuracy,. We recommend that large alligator clips be
attached to the ends of the thermocouple leads for accurate placement within the oven cell.
Why Two Thermocouple Leads?
A single lead attached to the center of the oven cell does not give you a good understanding of
what is happening in other parts of the oven. A customer will often claim that the oven is hotter on
one side than the other. Using two leads allows you to measure both sides of the oven cell at the
same time. Measuring multiple locations also allows you to ovoid opening your oven door once
testing has begun. Once you have begun testing, you can move freely from cycle to cycle
but never open the oven door. If you do, add an extra ten minutes to your testing.
The Long And Short Of It
The longer the test, the more accurate the results will be.
Regardless of the cycle selected, forty minutes is a minimum test period.
You cannot do a thorough test sequence in a shorter time. If time allows, testing all three bake
modes will give you the best averages. If time allows (1 1/4 hrs) the ideal test sequence should
look like this.
 Carefully discuss the customer’s problems to determine the problem
 Check ERC offset and record
 Install dual probes with alligator clips as specifi
ed
 Select Standard Bake and adjust to 350F.
 Record start and preheat tone time
