Item Function
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 item ). 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 9190A and 9190A-P 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 1.
STABLE ALARM turns on or turns off the audible Stable Alarm that sounds when the block
temperature is within the Stable Limit. See item .
CONTROL SENSOR
[-P Only]
sets the Calibrator to use the internal sensor or an external sensor to
control the block temperature. The Control Sensor setting has two options: Internal and Reference.
Note
Use of an external sensor such as a PRT can result in improved temperature accuracy
.
Internal tells the Calibrator to use the internal sensor for temperature control. In return, it relies on
its own calibration for accuracy.
Reference tells the Calibrator to use a PRT that is connected to the Reference Probe input
(REF PRT) for temperature control. In this mode, the temperature of the reference PRT is
measured and shown on the Main screen, and the block temperature is automatically adjusted so
that the temperature of the Reference PRT aligns with the SETPOINT.
