Ukusebenza

Amandla emitha 

1. Cindezela inkinobho yamandla ukuze uvule noma uvale imitha
2. Uma imitha ingavuli uma inkinobho yamandla icindezelwa noma uma uphawu lwebhethri ephansi luvezwa ku-LCD, shintsha ibhethri.

Ukucisha Okuzenzakalelayo (APO)

1. Imitha ifakwe isici sokuvala amandla okuzenzakalelayo (APO) esivala imitha ngemva kwemizuzu engama-20 yokungasebenzi. Isithonjana sivela ngenkathi i-APO ivuliwe.
2. Ukuze ukhubaze isici se-APO, kanye kanye cindezela futhi ukhulule izinkinobho ezithi RANGE/APO kanye ne-REC/SETUP. Cindezela bese ukhulula futhi ukuze uphinde wenze kusebenze isici se-APO.

• Iyunithi Yokulinganisa
  Cindezela inkinobho ethi UNITS ukuze ushintshe iyunithi yokulinganisa ukusuka ku-Lux kuya ku-Fc noma ukusuka ku-Fc kuya ku-Lux
• Ukukhethwa Kwebanga
  Cindezela inkinobho ethi RANGE ukuze ukhethe ububanzi bokulinganisa. Kunezinketho ezine (ububanzi) zeyunithi ngayinye yokulinganisa. Izithonjana zobubanzi zizovela ukuze zihlonze ububanzi obukhethiwe.

Ukuthatha Isilinganiso

1. Susa ikepisi elivikelayo lenzwa ukuze uveze i-dome yenzwa emhlophe
2. Beka inzwa endaweni evundlile ngaphansi komthombo wokukhanya ozolinganiswa
3. Funda ileveli yokukhanya kusibonisi se-LCD (ngokwezinombolo noma ngegrafu yebha).
4. Imitha izobonisa 'OL' lapho ukulinganisa kungaphandle kwebanga elishiwo imitha noma uma imitha isethwe kububanzi obungalungile. Shintsha ububanzi ngokucindezela inkinobho ethi RANGE ukuze uthole uhla oluhle kakhulu lohlelo lokusebenza.
5. Shintshanisa ikepisi yenzwa yokuvikela lapho imitha ingasebenzi.

Ukubamba Idatha

• Ukuze umise isibonisi se-LCD, cindezela okwesikhashana inkinobho ethi BAMBA. 'MANU HOLD' izovela ku-LCD. Cindezela okwesikhashana inkinobho ethi BAMBA futhi ukuze ubuyele ekusebenzeni okuvamile.

Inani eliphakeme

Umsebenzi we-Peak Hold uvumela imitha ukuthi ithwebule ukukhanya kokukhanya kwesikhathi esifushane. Imitha ingathatha iziqongo zehle ziye ku-10µS ngobude besikhathi.

• Cindezela inkinobho ye-PEAK ukuze wenze kusebenze isici se-Peak Hold. “I-Manu” kanye “ne-Pmax'' kuzovela esibukweni. Cindezela inkinobho ye-PEAK futhi bese kuvela okuthi “Manu” nokuthi “Pmin”. Sebenzisa 'Pmax' ukuze uthwebule iziqongo ezinhle. Sebenzisa 'Pmin' ukuze uthwebule iziqongo ezingezinhle.
• Uma inani eliphakeme lithwetshuliwe, inani nesikhathi esihlobene kuzohlala kusibonisi kuze kuqoshwe inani eliphakeme kakhulu. Isibonisi segrafu yebha sizohlala sisebenza sibonisa ileveli yokukhanya yamanje.
• Ukuze uphume kumodi yokubamba Okuphakeme futhi ubuyele kumodi evamile yokusebenza, cindezela inkinobho ethi PEAK okwesithathu.

Ubuningi (MAX) kanye nobuncane benkumbulo yokufunda (MIN)

Umsebenzi we-MAX-MIN uvumela imitha ukuthi igcine ukufundwa okuphezulu kakhulu (MAX) nokuphansi kakhulu (MIN).

1. Cindezela inkinobho engu-MAX-MIN ukuze wenze isici sisebenze. U-“Manu” kanye no-“MAX” azovela esibonisini futhi imitha izobonisa kuphela ukufundwa okuphezulu kakhulu okuhlangatshezwane nakho.
2. Cindezela inkinobho engu-MAX-MIN futhi. “I-Manu” kanye nethi “MIN’ kuzovela esibukweni futhi imitha izobonisa kuphela ukufundwa okuphansi okuhlangatshezwane nakho.
3. Uma i-MAX noma i-MIN ithwetshuliwe, inani nesikhathi esihlobene sizohlala kusibonisi kuze kuqoshwe inani eliphezulu. Isibonisi segrafu yebha sizohlala sisebenza sibonisa ileveli yokukhanya yamanje.
4. Ukuze uphume kule modi futhi ubuyele kumodi yokusebenza evamile, cindezela inkinobho engu-MAX-MIN okwesithathu.

Imodi Ehlobene

Umsebenzi Wemodi Ehlobene uvumela umsebenzisi ukuthi agcine inani eliyireferensi kumitha. Konke ukufundwa okubonisiwe kuzohlotshaniswa nokufundwa okugciniwe.

1. Thatha isilinganiso, futhi lapho inani lesithenjwa olifunayo liboniswa, cindezela inkinobho ye-REL.
2. "I-Manu" izovela esibukweni se-LCD.
3. Konke ukufundwa okuzolandela kuzolungiswa ngenani elilingana nezinga lereferensi. Okwesiboneloampfuthi, uma izinga lesithenjwa lingu-100 Lux, konke ukufundwa okuzolandela kuzolingana nokufunda kwangempela kukhishwe u-100 Lux.
4. Ukuze uphume kumodi yesihlobo, cindezela inkinobho ethi REL.

I-LCD Backlight

Imitha ifakwe isici se-backlight esikhanyisa isibonisi se-LCD.

1. Cindezela inkinobho ye-backlight ukwenza kusebenze ukukhanya kwangemuva.
2. Cindezela inkinobho ye-backlight futhi ukuze ucime isibani sangemuva. Qaphela ukuthi i-backlight izocisha ngokuzenzakalelayo ngemva kwesikhathi esifushane ukuze wonge amandla ebhethri.
3. Umsebenzi we-backlight usebenzisa amandla ebhethri engeziwe. Ukuze wonge amandla, sebenzisa isici se-backlight kancane.

Iwashi kanye no-Sample Linganisa Ukusethwa

Kule modi, izinkinobho ▲ kanye ▼ zomcibisholo zizovumela ukulungiswa kwamadijithi akhethiwe (acwebezelayo). Izinkinobho ◄ kanye nethi ► zizoskrolela ekukhetheni okulandelayo noma kwangaphambilini.

1. Nika amandla imitha, bese ucindezela kanye nezinkinobho ze-REC/SETUP kanye ne-UNITS kanyekanye ukuze ufake imodi yokusetha. Isibonisi samahora sizokhanya.
2. Lungisa futhi udlule ekukhetheni ngakunye njengoba kudingeka.
3. Cindezela bese ubamba izinkinobho ze-REC/SETUP kanye ne-UNITS kanyekanye ukuze uphume kumodi yokusetha.

I-oda lokukhetha elinokukhanya (isithonjana) lithi: 

• Ihora (0 kuya ku-23) 12:13:14 (Isikhathi)
• Iminithi (0 ukuya ku-59) 12:13:14 (Isikhathi)

• Inyanga (1 kuya ku-12) 1 03 10 (Usuku)
• Usuku (1 kuya ku-31) 1 03 10 (Usuku)
• Usuku lweviki (1 kuya ku-7 1 03 10 (Usuku)
• Unyaka (00 kuya ku-99) 2008 (Unyaka)

99 Inkumbulo Yamaphuzu

Kungafika ekufundeni okungu-99 kungagcinwa mathupha ukuze kusetshenziswe kamuva viewngqo kwi-LCD yemitha. Le datha ingadluliselwa ku-PC kusetshenziswa uhlelo lwesofthiwe olunikeziwe.

1. Uma imitha IVULIWE, cindezela inkinobho ethi REC okwesikhashana ukuze ugcine ukufundwa
2. Isithonjana sokubonisa se-MEM sizovela nenombolo yekheli lememori (01 -99)
3. Uma inkumbulo yokufunda 99 igcwele, uphawu lwe-MEM kanye nenombolo yendawo yememori ngeke ivele
4. Kuya view ukufundwa okugciniwe, cindezela bese ubamba inkinobho ethi LOAD kuze kuvele uphawu lwe-MEM oluhambisana nenombolo yekheli lememori.
5. Sebenzisa izinkinobho zomcibisholo waphezulu naphansi ukuze uskrole ekufundeni okugciniwe.
6. Ukuze usule idatha, cindezela futhi ubambe izinkinobho REC/SETUP kanye ne-LOAD kanyekanye kuze kuvele 'CL' endaweni yenkumbulo ku-LCD.

16,000 Point Datalogger

I-HD450 ingaqopha ngokuzenzakalelayo ukufundwa okungafika ku-16,000 kumemori yayo yangaphakathi. Kuya view idatha, ukufundwa kufanele kudluliselwe ku-PC ngesofthiwe enikeziwe.

1. Ngokusebenzisa imodi ye-ISETHA, setha isikhathi nesiample rate. Okuzenzakalelayo sampisilinganiso yisekhondi elingu-1.
2. Ukuze uqale ukurekhoda, Cindezela futhi Ubambe inkinobho ye-REC kuze kube yilapho isithonjana sesibonisi se-MEM siqala ukucwayiza. Idatha izogcina ku-sampkala ngenkathi isithonjana se-MEM sicwayiza.
3. Ukumisa ukurekhoda. Cindezela futhi Ubambe inkinobho ye-REC kuze kube yilapho isithonjana se-MEM sinyamalala.
4. Uma imemori igcwele, i-OL izovela njengenombolo yememori.
5. Ukuze usule inkumbulo, imitha icishiwe, cindezela bese ubamba inkinobho ethi REC bese ucindezela inkinobho yamandla. "dEL" izovela kusibonisi. Khipha inkinobho ye-REC lapho i-“MEM” ivela esibukweni, inkumbulo isuliwe.

I-USB PC Interface

Incazelo 

Imitha ye-HD450 ingaxhunywa ku-PC ngesixhumi esibonakalayo se-USB. Ikhebula le-USB, kanye nesofthiwe ye-WindowsTM, ifakiwe nemitha. Isoftware ivumela umsebenzisi ukuthi:
