INTRODUCTION
Nagman’s Medium Temperature Dry Block Calibrator
– Model 650-H is used for calibrating RTD’s,
Thermocouples, Temperature Switches, Temperature
Indicators etc.
Temperature controller Nagman 172 is used in this
instrument, having two levels in the temperature
profile determined as RAMP and SOAK between Set
temperature point (SP) and Set time. At the time of
calibration “RUN” indication is active in the controller
continuously shows the current “Block” temperature.
Desired temperature is set in the Nagman 172
controller by “P” key for accessing the input
parameter and pressing
/
to increase and
decrease the value.
Proper use of the instrument will provide accurate
calibration of temperature sensors.
