<< Altek Milliamp CalibratorsAltek 134-2
PocketCal mA Calibrator
|
- Basic Milliamp Functions
Source 0.00 to
24.00 mA or -25.0 to 125.0%, read mA or percent to
24.00 mA, simulate 2-wire transmitters, power and
measure 2-wire transmitters.
- Basic Accuracy
±( 0.08% of 24 mA Span + 1
LSD)-Source to read within 0.03 mA.
- Quik-Chek Outputs HI and LO push-buttons for
instant output of 20.00 or 4.00 mA. Speed sensitive
digital potentiometer adjusts output from any
QUIK-CHEK position for valve stroking.
Power Up Transmitters Drives to 700 ohms
loads.
- Long Battery Life
Sources 12 mA for over 22 hours, 20 mA for over
16 hours. Turns itself off after 30 minutes.
- Dependable Operation
Fuseless protection to
120 V AC/DC.

The Altek
Pocketcal 134-2 will check, calibrate and measure all of
your current signal instruments in a 4 to 20 milliamp DC
loop. Use at every point in your loop. Source & read
0.00 to 24.00 mA, Simulate a two-wire transmitter or use
the 134-2 to simultaneously power & measure your 2-wire
transmitters. Toggle the display to show milliamps or
percent of 4 to 20.
Calibrate recorders, digital indicators, stroke valves
or any other instruments that get their input from a 4
to 20 mA loop. Easily set any value to within 0.01 mA
with the speed sensitive digital potentiometer.
The "Quik-Chek" pushbuttons provide rapid checking of
4.00, 20.00 and a third point between 0.00 to 24.00 mA.
Check loop wiring and receivers by using the 134-2 in
place of a 2-wire transmitter. Simulate a changing
process input to check loop response and control
settings. The 134-2 uses any loop power from 3 to 42 VDC.
Check controller outputs or measure the milliamp signal
anywhere in the loop. The 134-2 measures 0.00 to 24.00
mA signals with much greater accuracy than a typical
multimeter. Toggle the display to show milliamps or
percent of 4 to 20.
Simultaneously measure the output of a 2-wire
transmitter while using the internal batteries to supply
up to 14 VDC to power the transmitter. Handy for
checking transmitters in the field or on the bench. |
