At your risk.
This is the main Pleiades portable digital multimeter, auto range, auto power off.
Electrolytic capacitors inside:
1x 22μF 22V 105oC
3x 10μF 25V 105oC
ICs
KAD7001 445B
Philips 74HCO4D UB515MME CRn9514 B
It uses only 2 AAA batteries which last for ages
When newly bought a short circuit on probes did not zero the ohms reading. It was thought there was a problem possibly due to accidentally connecting voltage while taking a resistance reading.
It turned out the factory probes were of lesser quality.
With new probes CAT.III it zeros exactly.
Yesterday a liquid crystal display problem developed after it dropped from only a few inches. Some segments would not lit.
Everything had been taken apart. LCD dismantled, the elastic connectors washed and cleaned. They were air dried as even a cotton towel leaves cotton residue at hands.
It turned out that some small dust, paper particle found itself between LCD and its contacts.
Initially LCD did not operate satisfactorily. 2 small folded paper shims were inserted between the LCD lock fasteners and LCD structure near the contacts side so that contact fit to LCD crystal is much tighter. Factory had installed such a shim which gave out the idea on improving that way. Now perfectly operates.
