Altek 211 RTD Calibrator lets you simulate and read RTDs
over the entire industrial temperature range. Use with
transmitters, single & dual channel recorders,
controllers, alarms and indicators. Switch between four
Pt 100, one Pt 1000, one Cu 10, two Ni RTD curves or
ohms ranges from 0.00 to 410.00 and 0.0 to 2010.0.
Field customize the Model 211 to lock-in 1° resolution,
fixed ° C or ° F or front selectable ° F/° C operation.
Read and simulate 2-wire and automatically compensate
for 3-wire RTDs with built-in leads. A plug-in lead is
supplied for 4-wire RTD measurements. RTD types may be
selected each time the unit is turned on. If you always
use one RTD curve, lock-in the selected RTD type with
the internal DIP switch to prevent accidental change to
an unwanted RTD type.
Resolution is 0.1° C or F simulating the full range of
Pt 100 ohm RTDs into devices supplying a continuous
excitation current of 0.09 to 1.1 mA. From 1.1 to 5.800
mA continuous excitation current the 111 resolution
automatically adjusts to 1° C or F. Ohms range provides
0.01 ohm resolution from 0.00 to 410.00 ohms which
automatically switches to 0.1 ohm resolution for
continuous excitation currents above 1.1 mA.
"QUIK-CHEK" function stores three output temperatures
for real convenience. The Model 211 simulates key
temperatures for repetitive calibrations. Turn the knob
to check trip points, controller action or hysteresis.
The fast response 211 sets quickly without overshoot.
Memory is retained even when power is off.
Altek 211 display gives you fast, accurate
temperature measurement with 0.1 and 1 degree or with
0.01 and 0.1 ohm resolution. Two, three and four wire
hookups assure accuracy in short or long cable runs.
Open RTDs and leads are detected and indicated on the
LCD display. Two readings per second track fast moving
temperatures.
"MAX" and "MIN" memories are continuously updated from
turn-on or whenever the "RESET" button is pressed. Model
211 gives you a handy tool to monitor temperatures for
drift or control deviation. Just flip the Quik-Chek
switch to display the minimum and maximum temperature
measured since reset.
