Hioki-3554

Re-designed circuit for super resistance to noise Store up to 4800 sets of battery data in internal memory and manage records on your PC Auto-hold and Auto-store functions make measurement and recording simple and hands-free Strengthened ( and user-exchangeable) probe tip means less chance of breakage and more constant workflow Hioki 3554 BATTERY HiTESTER quickly diagnoses the condition of lead-acid batteries by measuring the internal resistance and voltage of batteries used for backup in UPSs and emergency power supplies in the field, without shutting down the system. The four-range design covering 0.001 m© to 3.100© enables easy measurement of the mid- and high-capacity sealed lead-acid batteries in these devices. By simply specifying primary and secondary limits for the battery resistance and the minimum voltage threshold, the battery tester quickly displays Pass, Warning or Fail based on the combination of reference values, for fast and accurate assessment. Measurements AC voltage, temperature, resistance Display LCD Sampling Rate Once per second Averaging Function OFF, 4, 8 or 16 times Input Overflow [ OF] is displayed Constant current fault detection [ ----] is displayed Open-circuit terminal voltage 5V/ max Auto power off 10 mins unless data transmission is active Comparator Settings First and second resistance limits and low voltage limit Number of Comparator Settings 200 Sets Comparator Output LCD display of PASS, WARNING, or FAIL.
