  • All 4 to 20 mA Loop Functions— Source 0.00 to 24.00 mA or -25.0 to 125.0% read mA or percent to 52.00 mA, simulate 2-wire transmitters, measure -99.99 to 99.99 volts DC power & read 2-wire transmitters.
  • Quik-Chek Switch— Select 4 or 20 mA output or 2-wire simulation. Accurate to ±0.006 mA.
  • Full Range 10 Microamp Resolution— Adjust 4 digit display to ±0.05% without range change.
  • Long Battery Life— 3x9 volt alkaline batteries source 20 mA for over 20 hours, 12 mA for over 33 hours; 2-wire simulate and read for 150 hours. Much longer than NiCd batteries or calibrators with a single 9 V battery!
  • Drive Capability— 1200 Ohms with current limited, fuseless protection to 135 V AC/DC.

Product Detail

Details

Altek 334A checks all loop signals, mA, % of Span and DC V. Saves time on every mA transmitter, recorder, alarm trip, I/P and computer/PLC you calibrate. Flip the QUIK-CHEK switch for instant outputs of 4 and 20 mA accurate to 0.006 mA, and trim your device in seconds.
