Six datasheet checks before you send an RFQ

A quote is only as good as the part number. These six checks use fields the catalog already prints. If a field is missing on the model you want, ask for the datasheet instead of guessing.

One: the part number matches the work. Fluke 101 is a digital multimeter. Fluke 301A is a clamp meter. They are not alternates.

Two: True-RMS is printed when you need it. Fluke 175, Metravi 23S-TRMS and Kusam-Meco KM 235 state TRMS. Silence is not a yes.

Three: the safety category is printed on that meter. Fluke 107 is listed as CAT III. The Fluke 101 photo is marked 600 V CAT III. The Fluke 175 photo prints CAT III 1000 V and CAT IV 600 V together. Do not copy one model’s marking onto another.

Four: insulation test voltage is printed. Kyoritsu KEW 3125B states 250 V to 5000 V. WACO-3125A states 5000 V. A line that only says “digital insulation tester”, such as Metravi DIT-321, still needs the voltage table from its datasheet.

Five: the earth method is printed. Kyoritsu KEW 4105A states 2-pole and 3-pole. Metravi CET-01 is clamp-on. Metravi PRO ERT-1602 adds soil resistivity.

Six: panel size and class are printed. Selec MVA591-30A-230V is 48 × 48 mm, ±1% of full scale, up to 30 A. Selec MFM384-C-CE-CL05 is a multifunction meter, class 0.5S, with RS485. Send those six answers with the quantity and city.
