• K-uhlobo lwe-thermocouple olusebenzayo

Ukunikezwa kwamandla kanye ne-Fuse, intambo yamandla, ukushintshwa kwe-Test probe

Ukulungiselelwa kokunikezwa kwamandla

1. Vula iswishi ebomvu endaweni ehambisanayo
   Ukusetha izinyathelo:
   • Khipha intambo yamandla
   • Vula iswishi ebomvu endaweni ehambisanayo
   • Izikhundla ezikhethekayo ziboniswa ngezansi
2. Ukushintshwa kwe-fuse
   1. Khipha imikhondo yokuhlola ethuluzini.
   2. Vala ukunikezwa kwamandla kwethuluzi
   3. Vula i-fuse housing nge-screwdriver.
   4. Kushintshwe i-fuse kwafakwa entsha.
3. ukuhlola esikhundleni se-probe
   uma ukwahlukanisa ku-probe konakalisiwe, kushintshe.
   ISEXWAYISO : ama-probe assemblies azosetshenziselwa izilinganiso AMAINS azolinganiswa nge-CAT II 600V kanye ne-lOA ngokuya nge-EN 61010-031 noma okungcono.
4. Ukushintshwa Kwentambo Yamandla
   uma ukwahlukanisa entanjeni kagesi konakalisiwe, kushintshe.
   Sicela usebenzise i-AC 250V, i-lOA noma intambo yamandla engcono.
