Description: DIGITAL THERMOMETER
Information:
                                    The Fluke Model 2100A is a digital, thermocouple
thermometer, employing the dual-slope integration technique,
and capable of making precise temperature measurements in
either degrees Fahrenheit (°F) or degrees Celsius (°C). The
instrument is fully guarded and features a fully isolated input.
1-3. The 2100A has a five-digit readout (plus sign) capable
of indicating up to ±3999.9 degrees. However, the range of
the instrument is determined by the type of thermocouple
used. The instrument can be ordered, configured to use any
of the following types: J, K, T, E, R and S. Table 1-1 shows
the temperature ranges for each of these types. Resolution
of the instrument is 0.1 degree, except in instruments using
a type R or a type S thermocouple and indicating in °F, when
resolution is 0.2 degrees. The readout features 0.5 inch
characters, fixed decimal point, and leading-zero
suppression for the two most significant digits.
1-4. The 2100A is available in three basic models: the
2100A—03, the 2100A-06, and the 2100A-10. The
2100A--03 is a single-point instrument (one input); the
2100A-10 is a multi-point instrument (10 inputs). Both of
these models are tailored at the factory to use only one
specific type of thermocouple. Once tailored, the 2100A—
03 and 2100A—10 are limited to that one type, but can be
converted to any one of the other five at any time, by means
of a conversion kit.
1-5. The 2100A—06 is a multi-type instrument. It is tailored
to accept inputs from any of the six different types of
thermocouple, but only one type at any given time.
(The 2100A—06 is not a multi-point instrument). In effect,
the 2100A—06 is a 2100A—03 that can be rapidly converted to
accept different thermocouples, by means of integral
selector switches, rather than conversion kits. For valid
indications from a 2100A—06, the selector switch depressed
must correspond to the type of thermocouple being used.
In addition, the 2100A—06 can accept linearized voltage
inputs on either of two selectable mV ranges directly from
other transducers, such as bridge-connected strain gauges.
Table 1-2 is a summary of the differences between the three
basic models of the 2100A.
