General description
Easy to use
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.
Source milliamps
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.
Recall output setting
The "Quik-Chek" pushbuttons provide rapid checking
of 4.00, 20.00 and a third point between 0.00 to 24.00
mA.
Calibrate using loop power
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
45 VDC.
Read loop current
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.
Power and measure 2-wire transmitters
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.
