2 Introduction
The Hart Scientific 9140 Mid-Range Field Calibrator may be used as a portable
instrument or bench top temperature calibrator for calibrating thermocouple
and RTD temperature probes. The 9140 is small enough to use in the field, and
accurate enough to use in the lab.
The instrument features:
•
Rapid heating and cooling
•
Interchangeable multiple hole aluminum probe sleeves
•
Convenient hand strap
•
RS-232 interface capability
Built in programmable features include:
• Temperature scan rate control
• Temperature switch hold
• Eight Setpoint memory
• Adjustable readout in °C or °F
The temperature is accurately controlled by Hart’s hybrid analog/digital con-
troller. The controller uses a precision platinum RTD as a sensor and controls
the well temperature with a solid state relay (triac) driven heater.
The LED front panel continuously shows the current well temperature. The
temperature may be easily set with the control buttons to any desired tempera-
ture within the specified range. The instrument’s multiple fault protection de-
vices insure user and instrument safety and protection.
The 9140 dry-well calibrator was designed for portability, low cost, and ease of
operation. Through proper use the instrument will provide continued accurate
calibration of temperature sensors and devices. The user should be familiar
with the safety guidelines and operating procedures of the calibrator as de
-
scribed in the instruction manual.
