Comparative output Select from Normal, Area and Rank Output form 5 kinds（HH, HI, GO, LO, LL） ◎ Wavy comparision function Set HI/LO limit set value of 2048 points per pattern (up to 8 patterns can be set). After starting, this function serves to check whether indicated value is within HI/LO limit set value or not for comparison in real time and outputs results. ? Waveform comparison (X axis = time) Comparision output = Y axis HI, GO and LO ? Waveform and displacement comparison (X axis = displacement) Comparison output = Y axis HI, GO and LO, X axis HI and LO (Displacement output) ◎ I/O function OUT1, OUT2, OUT3 Execute the comparison output OUT4, OUT5 Output signal changes by selecting the each function. Comparison output OUT1 (No.1) OUT2 (No.2) OUT3 (No.3) OUT4 (No.4) OUT5 (No.5) Ach meter HH HI GO LO LL Bch meter HH HI GO LO LL 2ch meter HI (Ach) LO (Ach) GO(※) HI (Bch) LO (Bch) Waveform comparison Ach HI (Ach) LO (Ach) GO (Ach) － － Waveform comparison Bch － － GO (Bch) HI (Bch) LO (Bch) Waveform & displacement comparison HI (Ach) LO (Ach) GO (Bch) HI (Bch) LO (Bch) * When HI and LO of both channels are only turning off, it becomes turning on.
