It features an accuracy of 0.005% of range and is suitable for use in the shop, plant, or field. A key capability of the 541 is its totalizer function, which eliminates the need for a stopwatch by automatically stopping after sending a pre-selected number of pulses, saving significant troubleshooting time\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e", "published_at":"2026-01-16T11:43:26", "created_at":"2026-01-16T11:43:26", "vendor":"Pie Calibration", "type":"Electrical Testers", "tags":[], "price":391034, "price_min":391034, "price_max":391034, "price_varies":false, "compare_at_price":null, "compare_at_price_min":0, "compare_at_price_max":0, "compare_at_price_varies":true, "all_variant_ids":[45794732474558], "variants":[{ "id":45794732474558, "product_id":8672299647166, "product_handle":"pie-calibration-541-frequency-calibrator-with-totalizer", "title":"Default Title", "option1":"Default Title", "option2":null, "option3":null, "sku":"PIECAL 541", "requires_shipping":true, "taxable":true, "featured_image":null,"image_id":null, "available":true, "name":"Pie Calibration 541 Frequency Calibrator with Totalizer - Default Title", "options":["Default Title"], "price":391034, "weight":2268, "compare_at_price":null, "inventory_quantity":0, "inventory_management":"shopify", "inventory_policy":"continue", "inventory_in_cart":0, "inventory_remaining":0, "incoming":null, "next_incoming_date":null, "taxable":true, "barcode":null}], "available":true,"images":["\/\/kingswayinstruments.com\/cdn\/shop\/files\/Piecal541.jpg?v=1768589099"],"featured_image":"\/\/kingswayinstruments.com\/cdn\/shop\/files\/Piecal541.jpg?v=1768589099", "options":["Title"], "url":"\/products\/pie-calibration-541-frequency-calibrator-with-totalizer"}
