Calibrate
and troubleshoot all the signals in a standard 4 to 20
milliamp process control loop with Altek’s Model 434
Milliamp Calibrator. A 24 mA Source, mA meter, 2-Wire
Transmitter Simulator and a DC Volt meter in one compact
unit enables a single tool to perform most calibration
and troubleshooting functions.
Calibrate controllers, recorders or other devices in 4
to 20 or 0 to 20 mA loops. Six "AA" batteries provide
hours of continuous use. The batteries last several time
longer than calibrators with a single 9V battery!
Optional AC adapter for continuous use.
Check out the response of a loop by using the Model 434
in place of a 2-wire transmitter. The Model 434
modulates the current passing through the loop just like
a transmitter, but with manual control.
Simultaneously supply power to a 2-wire transmitter
while displaying the 4-20 mA output signal. The Model
434 supplies a nominal 24 Volts DC to the 2-wire
transmitter while displaying the transmitter’s output.
Check 24 Volt loop supplies and batteries using the
built-in voltmeter. Verify instruments with 1-5 Volt
outputs.
Save time with every calibration by using the advanced
features of the Model 434. Instantly recall any three
output settings with the handy QUIK-CHEK switch. All
output settings are remembered, even with the power off.
Be in two places at once by using the Model 434’s AUTO-CHEK.
Connect behind the panel or replace a transmitter, then
check the output in front of the panel or another remote
location within the loop. Choose 2, 3, 5 or 10 output
steps from 5 to 900 seconds to match your calibration
setup. Use the automatic Ramp/Soak to simulate a running
process and check valves for smooth operation. |
