# Precise 3-1/2 Digit LCD - ± 0.1% 4 - 20 mA SPAN in Milliamps or Percent
# \"QUIK-CHEK\" Zero and Full Scale - Switch 4.00, 20.00 mA or Continuous Dial
# Pocket Size & Lightweight - 12.5 oz. (0.35 kg)
Description:
Altek\'s triple function Model 234 Signal Analyzer combines a self contained 0-24 mA Source, a 2-Wire Simulator, and a large LCD Digital Readout in a single pocket sized instrument.
Dual Range allows display of each function in Percent of 4-20 mA signal, as well as directly in Milliamps. Percent range displays minus 25.0% to plus 125.0% with 0.1% resolution. Milliamp range displays from 0.00 to 19.99 mA with 10 microamp resolution. Accruacy is ±0.1% of 4 - 20 mA ±1/2 lease significant digit.
\"QUIK-CHEK\" switch provides instant zero (4.00 mA) and full scale (20.00 mA) settings in bouth Source and 2-Wire modes. Output in the Percent range displays 00.0% and 100.0% for \"QUIK-CHEK\" settings. Dial position selects a continuously adjustable 10 turn potentiometer to allow fast, easy setting to any exact value.
Source Mode uses built-in batteries to provide 0-24 mA into any load from 0-1000 ohms. 3 nine volt alkaline batteries provide over 20 hours of continuous 20 mA output...more than three months of typical use. An optional AC adapter (not included) plugs in for continuous bench use. True current source maintains set output independent of load. 2-Wire Transmitters can be Powered and Measured in this mode.
2-Wire Simulator mode modulates external power to pass 4 - 20 mA. The Altek Model 234 uses any Loop Power from 2 to 100 volts DC. True current design maintains set current independent of voltage or load changes.
Read mode displays either Milliamps or Percent of 4 -2 0 mA signal. Maximum Read current is limited to (nominally) 25 mA to minimize the possibility of damaging the calibrator or the loop to be calibrated. Special protective circuitry withstands accidental misconnection in any mode without fuses.
Display digits are 0.350\" (9 mm) high for readability from across the room. Non-glare Liquid Crystal Display is readable in any light...even in direct sunlight. The digital measuring circuit is independent of the current adjustment and measures the actual input or output.
The Altek Model 234 is rugged, yet lightweight and pocket sized. Latest LSI circuitry and wide temperature range components make the Model 234 ideal for use in the field, control room and shop.
Benchtop Accuracy in a Toolbox Calibrator assures fast, precise setting of current trips, recorders, controllers, loggers, computers and final control elements.
