產品特色············································································································································
-
測量輸出同時進行并相互之間隔離，互不干擾。
-
完善的保護功能。防止誤操作。輸入輸出接線端子保護至最高40V，24V電源短路時輸出30mA。
-
測量熱電阻采用工業常用的三線制方式，消除導線誤差。測量準確可靠。
-
熱電偶、熱電阻測量和輸出時溫度值和對應的毫伏值、電阻值同時顯示。
-
熱電偶有自動或手動設置冷端溫度補償功能。方便熱電偶類儀表或設備的校準。
-
所有的功能都有百分比顯示，并且量程范圍可隨意設定。
-
輸出設定數值有三種方式：1、按位增減輸出值。2、按步階增減，步階值可設置。3、編程輸出。按預先編制的數值輸出。每個功能可設置10個數據。方便批量校準。
-
大屏幕顯示器，帶背光，輕松讀取數據。
-
測量時，可清除零點漂移。
-
自校準功能，無需返廠校準
-
交流220V或內部大容量電池供電，現場使用時間長。
