Specifications
*1: 140 kHz applies when sine and cosine signals within a designated range are applied to MJ820/821. Max. response frequency may be lower than 140kHz with change in input signal level or off-set value.
*2: Speed alarm is triggered when max. response speed is exceeded or at the time of erroneous counting due to noise. Level warning is triggered when the sine and cosine signal input level is lower than 0.6 to 0.5Vp-p.
*3: All LEDs light at the next power-on in case, at the time of data compensation, the compensated data was not correctly backed up.
