Environmental Conditions
Calibrate this instrument under laboratory conditions. We recommend calibration
at 23
Controller may be calibrated at its intended use temperature if this is within the
specified operating temperature range of 0 to 40
Warm Up
The LDT-5525 Temperature Controller should be allowed to warm up for at least 1
hour before calibration.
