 VERNIER ME ERROR KYU AATA HAI, ERROR KE TYPE, OR UNKO KAISE THIK KARTE HAI:-

1. VERNIER ERROR KYA HOTA HAI :-

  DOSTO JAISA KI AAP SAB KO PTA HAI, VERNIER CALIPER EK BAHUT HI EASY WAY ME READING DENE WALA EK MEASURING INSTRUMENT HAI. VRNIER CALIPER USE KRNA BAHUT HI EASY HAI. VERNIER CALIPER KO USED KRNE KE LIYE HUME MOSTLY BS USKI READING KAISE PADHNI HAI BSS YE PTA HONA CHAHIYE. TO KOI BHI WORKER AASAANI SE READING LE SKTA HAI.

DOSTO KAYI BAAR KYA HOTA HAI, SPOUSE KIJIYE KISI JOB KA DIAMETER 30 MM HAI, OR JAB KISI VERNIER ME ERROR AA JATA HAI TO ERROR AANE SE BASICALLY VERNIER SIZE YA TO KAM BTATA HAI, YA FIR JYADA BTATA HAI, AGR EK VERNIER JOB KA SIZE 30 MM SE JYADA BTA RHA HAI TO SIMPLE SI BAAT HAI KI VERNIER +VE ERROR HAI, OR AGAR VERNIER USI JOB KA SIZE KAM BTA RHA HAI TO USME -VE ERROR HAI.

 JAB KISI ERROR AAYE  VERNIER KO USE KRTE HAI, TO US SE COMPANY KO NUKSAN HOTA HAI,  JISKE KAARAN COMPANY ME REJECTION HONE KE CHANCE BADHTE HAI. OR KOI BHI COMPANY YE NHI CHAHTI KI, REJECTION HO, ESILIYE VERNIER KO USE KRNE SE PHLE EK BAAAR JAROOR CHECK KR LE, KI VERNIER KI ZERO SET HAI YA NHI, AGR VERNIER KI ZERO SET HAI TO AAP WORK SHURU KR SKTE HAI, AGAR NHI HAI TO SABS E PHLE AAP VERNIER KI ZERO SET, USKE BAAD HI WORK KO SHURU KARE.

2. VERNIER KI ZERO KAISE SET HOTI HAI :-

DOSTO JAB BHI HUM LOG VERNIER KO USE KRTE HAI TO ZERO SET KRNA SBSE JAROORI HOTA HAI, AGR HUM ZERO KO SET NHI KARTE HAI TO, HUME SIZE CHECK KRNE ME PROBLUM AA SAKTI HAI. ESILIYE VERNIER KO USE KARNE SE PEHLE EK BAAR ZERO ZAROOR CHECK KR LE.

VERNIER KO ZERO KAISE SET KARTE HAI -

 VERNIER KO JAB HUM USE KARTE HAI TO EK BAAR VERNIER KO HUM LOGBAND KRKE DEKHTE HAI MTLB ZERO KARKE DEKHTE HAI, JAISE HI HUM VERNIER KO BAND KARTE HAI TO MAIN SCALE OR VERNIER SCALE KI ZERO SE ZERO MATCHO JAATI HAI. JAISA KI AAP NEECHE DIYE DRAWING ME DEKH SKTE HAI.

ES DRAWING ME AAP DEKH SAKTE HAI KI MAIN SCALE OR VERNIER SCALE KI DONO ZERO AAP ME MATCH KAR RHI HAI ESLA MTLB YE HAI KI YE VERNIER ABHI EXACT SIZE YAANI ZERO PAR SET HAI. AGR ESKI ZERO ME KOI BHI PROBLUM HOTI TO YE ZERO ZERO MATCH NHI. ESILIYE JAB BHI V ERNIER SE KAAM KARE TO EK BAAR THIK ESI TARAH SE VERNIER KI ZERO KO JAROOR SET KAR LE. TAAKI AAPKO JOB KI READING LENE ME KOI PROBLUM NA AAYE.

3. VERNIER ME ERROR KE KITNE TYPE HOTE HAI :-

DOSTO VERNIER CALIPER ME JAB BHI ERROR AATA HAI TO HUME BILKUL BHI PTA NHI CHLTA, ESILIYE VERNIER KO TIME TO TIME INSPECTION YA  CHECK KRTE RHE, YA FIR CHECK KRWATE RHE , TABHI HUME ERROR KA PTA CHAL SKTA HAI, VERNIER ME BASICALLY DO TYPE KA ERROR AATA HAI, DONO ERROR DOWN MW LIKHE HAI-

1. NEGATIVE ERROR

2. POSITIVE ERROR

NEGATIVE ERROR ME VERNIER CALIPER KISI BHI SIZE KO KAM BTANA SHURU KR DETA HAI, FOR EXAMPLE KISI JOB KO [JISKA SIZE / DIA 30 MM HAI] AAP CHECK KRTE HAI, OR CHECK KRNE PAR  USKA SIZE 29.57 AATA HAI, JABKI JOB KA ORIGINAL SIZE 30 MM HAI TO AISI SITUATION ME VERNIER KA ERROR ES TYPE SE HOGA-

                JOB ORIGINAL SIZE - 30.000 MM

                        CHECKED SIZE - 29.570

                                    SO THAT - 30.000 - 29.570  = 

                                                                      0.630 MM NEGATIVE ERROR

TO DOSTO ES PARKAR SE HUME NEGATIVE ERROR KA PTA CHALTA HAI. JAB BHI KISI VERNIER ME NEGETIVE ERROR HO, TO ERROR SIZE NIKAL KAR, JOB KA SIZE MAAP LE USKE BAAD TOTAL ME ME NEGATIVE ERROR KO PLUS KAR DE -

                              ERROR SIZE - 0.630 MM

                         CHECKED SIZE - 29.570 MM

SO TOTAL CORRECT SIZE  IS - 29.570 + 0.670 = 

                               TOTAL SIZE - 30.000 MM

ES PARKAR SE HUM SIZE KO COREECT CHECK KR SKTE HAI. BAS HUME DHYAAN SE ERROR SIZE KO NIKALNA HAI, USKE BAD AAP AASAANI SE ERROR CHECK KR SKTE HAI.

POSITIVE ERROR ME VERNIER CALIPER KISI BHI SIZE KO JYADA YA FIR AAM LANGUAGE ME KAHE TO +  BTANA SHURU KR DETA HAI, FOR EXAMPLE KISI JOB KO [JISKA SIZE / DIA 30 MM HAI] AAP CHECK KRTE HAI, OR CHECK KRNE PAR  USKA SIZE 30.57 AATA HAI, JABKI JOB KA ORIGINAL SIZE / DIA 30 MM HAI TO AISI SITUATION ME VERNIER KA ERROR ES TYPE SE HOGA -

               JOB ORIGINAL SIZE - 30.000 MM

                        CHECKED SIZE - 30.570

                                    SO THAT - 30.570 - 30.000  = 

                                                                                0.570 MM POSITIVE ERROR

                                                     

TO DOSTO ES PARKAR SE HUM LOG POSITIVE  ERROR KA PTA LGATE HAI. JAB BHI KISI VERNIER ME POSITIVE ERROR HO, TO ERROR SIZE NIKAL KAR LIKH LE, OR JOB KA SIZE CHECK KR LE USKE BAAD TOTAL CHECKED SIZE  ME SE POSITIVE  ERROR KO GHTA YA FIR KAHE TO ( - )  KAR DE -

                               ERROR SIZE - 0.570 MM

                         CHECKED SIZE - 30.570 MM

SO TOTAL CORRECT SIZE  IS - 30.570 - 30.000 = 

                               TOTAL SIZE - 30.000 MM

TO DOSTO ES PARKAR SE HUM SIZE KO COREECT CHECK KR SKTE HAI. BAS HUMEEK BAAT KA DHYAAN RAKHNA HAI, KI HUME  DHYAAN SE ERROR SIZE KO NIKALNA HAI, USKE BAD AAP AASAANI SE ERROR CHECK KR SKTE HAI.

4. VERNIER ME ERROR KYU AATA HAI :-

DOSTO JAB HUM LOG KOI NEW MEASURING INSTRUMENT BUY KRTE HAI TO USME KISI BHI TYPE KA KOI ERROR NHI HOTA HAI, NEW INSTRUMENT KA SIZE BILKUL ZERO HOTA HAI. MTLB USKI ZERO JO HAI VO ZERO PAR SET HOTI HAI. VERNIER ME ERROR AANE BAHUT SARE KAARAN HAI JAISE KI

1. VERNIER SE SIZE CHECK KARTE TIME VERNIER PAR FORCE DAAALNA ESKI VAJAH SE VERNIER KI SCALE APNI JAGAH SE HIL JATI HAI, JISKI VAJAH SE ERROR AATA HAI.

2. VERNIER CALIPER USW KRTE TIME ZAMEEN PAR GIR JANA DOSTO JAB KOI VERNIER UNCHAAI SE GIR JATA HAI TO, GIRNE KI VAJAH SE USKE SCREW LOOSE HO JATE HAI, YA CORNER TUT JATE HAI, JISKI VAJAH SE SIZE ME ERROR AANE KE CHANCHES BADH JAATE HAI.

3. VERNIER KO PROPER USKE PLACE PAR NA RAKHNA DOSTO AGAR HUM VERNIER KO USKI PROPER JAGAH PAR NHI RAKHTE HAI, TO OTHER INSTRUMENT KE PADAA RHNE KE KAARAN UNKE JAW KE BICH ME DHOOL MITTI YA LOHA AAADI EKATHE HO JAATE HAI, JISKI VAJAH SE VERNIER KE JAW PROPER FITT NHI HOTE TO SIZE ME ERROR AANE KA DARR RHTA HAI.

5. VERNIER ME ERROR SE KAISE BACH SKTE HAI :- 

DOSTO ERROR SE BACHNE KE LIYE HUM KUCH HIDAYTO KA DHYAAN RAKHAN PADTA HAI, VERNIER ME ERROR UPER LIKHE KAARANO KE KAARAN KI AATA HAI ENSE BACHNE KE LIYE HUM LOG YE KAM KAR SKTE HAI -

1. VERNIER CALIPER KO SAAVDAANI KE SATH USE KARE JIS SE US PAR DABAAV NA JAYE.

2. VERNIER CALIPER KO USE KARTE TIME YA VAISE BHI AGR KISI, MACHINE PAR PDA HAI TO, USE ZAMEEN PAR YA VAISE BHI KAHI BHI GIRNE NA DE, USE SMBHAAL KE RAKHE. OR PROPER PLACE PAR RAKHE. TAAKI USME MITTI YA KAN VGERH NA CHIPKE OR SIZE EKDAM OKAY RAHE.
