The unit could not be measured the Enzyme Tests such as GOT, GPT (340 nm filter) and Alkaline Phosphate (405 nm filter), but another tests can be measure as well.
In Filter Tension Check, I already followed the procedure as well and I can regulate the Trimmer P1 to obtain the (OPT.TENS) about 300 mV in 340 nm Filter, however, the OPT.TENS of the 340 nm Filter is not stable whenever I switch ON and then checked it again, it varies from 100 mV to 300mV. Sometimes it shows about 180 mV and then stable at near this point, but sometimes it shows about 250 mV and then stable at near this point, sometimes it shows other values.
But some of these Instruments are stable about 300 mV in 340 nm Filter. However all of these Instruments cannot be measured the Enzyme Tests
