PERAWATAN :

Selain dikalibrasi rutin ada baiknya untuk perawatan hariannya, setelah theodolite digunakan dilap dari kotoran atau debu yang menemepel menggunakan kain bersih atau majun dengan sedikit minyak kayu putih.

MANFAAT KALIBRASI :

Menjaga kondisi instrumen ukur dan bahan ukur agar tetap sesuai dengan spesefikasinya
Untuk mendukung sistem mutu yang diterapkan di berbagai industri pada peralatan laboratorium dan produksi yang dimiliki.
Bisa mengetahui perbedaan (penyimpangan) antara harga benar dengan harga yang ditunjukkan oleh alat ukur.
Kalibrasi Sebaiknya Dilakukan Secara Rutin & Berkala, Baiknya Alat Itu Dikalibrasi Per 6 Bulan Sekali Atau Waktu Pemakaian Alat Sudah Mencapai 1.000 jam.
