Calibration After Unit of Measurement Change
Check the instrument’s chamber temperature after changing
the unit of measurement to ensure the controller is measuring
it accurately.
Tools Needed:
A remote-monitoring thermocouple thermometer with a
NIST-traceable calibration certicate.
Series BIF, BIT, BOF, and BON
STEP 1: Place test materials in chamber, set program, and
press run for 3 seconds.
Compare the thermometer’s and probe’s temperature ratings against the
series operating range to ensure compatibility.
Series BOV: A ribbon lead thermocouple is required so as not to damage
the door seal. Additionally, the lead’s and probe’s materials must be rated for
temperatures up to ambient + 200OC (ambient + 392OF).
STEP 2: Insert thermometer probe into test hole.
Upon reaching the set temperature, insert thermometer probe
into the test hole.
STEP 4: Compare thermometer readings to set and present
temperatures. If SV1≠PV1≠TV1 or SV2≠PV2≠TV2, move
to STEP 5.
Make sure thermometer is stable. Then record the set temperature (SV1 &
SV2), present value (PV1 & PV2), and thermometer reading (TV1 & TV2).
STEP 3: Run test again at a second set temperature (SV2) at
least 10OC (18OF) greater than the rst.
Series BOV
STEP 1: Place test materials in chamber. Place temperature
probe in the center of the chamber. Close and lock
door. Set program and press run for 3 seconds.
STEP 3: Compare thermometer readings to set and present
temperatures. If SV1≠PV1≠TV1 or SV2≠PV2≠TV2, move
to STEP 4.
Make sure thermometer is stable. Then record the set temperature (SV1 &
SV2), present value (PV1 & PV2), and thermometer reading (TV1 & TV2).
STEP 2: Run test again at a second set temperature (SV2) at
least 10OC (18OF) greater than the rst.
Series BIC
STEP 1: Place test materials in chamber, set program, and
press run for 3 seconds.
STEP 2: Open test hole.
Upon reaching the set temperature, insert thermometer probe into the
test hole.
STEP 5: Compare thermometer readings to set and present
temperatures. If SV1≠PV1≠TV1 or SV2≠PV2≠TV2, move
to STEP 6.
Make sure thermometer is stable. Then record the set temperature (SV1 &
SV2), present value (PV1 & PV2), and thermometer reading (TV1 & TV2).
STEP 4: Run test again at a second set temperature (SV2) at
least 10OC (18OF) greater than the rst.
Thermometer probe’s outer diameter must be less than 8mm.
STEP 3: Insert thermometer probe into test hole.
The test hole is Ø25mm and located on the right
side of the oven.
