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-5500B Series Temperature Controller should be allowed to warm up for
at least 1 hour before calibration.
