Display unit  STN color LCD (320 dots × 240 dots)  
◎ Analog voltage output for monitor    
Ach input from strain gage  ±4.0 mV/V →Approx. ±6 V 
 
Bch input from instrumentation  ±0 V to 10 V → Approx. ±5 V
±0 mA to 20 mA → Approx. ±5 V 
◎ Comparative function    
Setting range  ±99 999  
Hysteresis ±0 to 9 999 (Not used in comparison output type ¨Area¨.) 
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.
