Item Function
1
SCAN RATE sets the rate at which the Calibrator heats or cools in degrees per minute (°C/
min or °F/min). The Scan Rate can be set from 0.1 °C/min to 500 °C/min (0.2 °F/min to
900 °F/min).
Note: The actual Scan Rate is limited to the natural rate the Product heats and cools.
This is less than the maximum Scan Rate setting.

STABLE LIMIT sets the temperature stability parameter the Calibrator uses to determine
when the temperature is stable enough to make a measurement.
When the temperature is within the range of the Stable Limit, the Calibrator shows a flat
bar (---) on the Main screen (Stability Status Indicator) and audibly sounds the Stable
Alarm if it is set to ON (see “Stable Alarm” below). The Stable Alarm sounds once per
SETPOINT.
Example: A specific calibration process requires the instrument to operate within ±0.1°C.
“0.1” is entered into the Stability Limit parameter. When the block temperature is within
±0.1°C, the Stability Status indicator on the Main screen changes to a flat line (---) and
the Stable Alarm sounds once.
Note: The LTR -90 should not be expected to operate better than the stability
specification found in the Specifications section of this manual. Thus, the
minimum setting of the Stability Limit should not be less than the stability
specification. See the “Base Unit Specifications” in Chapter 2.

STABLE ALARM turns on or turns off the audible Stable Alarm that sounds when the block
temperature is within the Stable Limit. See “Stable Limit” above.
