HR－8帶計算器的小型打印機配套使用，儀表內部有時鐘，時鐘可調，不測量時可顯示時間，機內設有鎳鎘電池，當儀表正常工作時，可對電池充電，斷電時，儀表自動進入保持狀態，由內部電池維持時鐘走時，可維持3個月以上。當儀表置在快速測量時，可自動打印測量時間及溫度值。7·備有隔離的并行BCD碼輸出口、4～20mA(1～5v)模擬量輸出口供用戶選擇，以便配接大屏幕顯示器或將測量結果送上位機。8·儀表內部主機板上設有分度號轉換短路子，供用戶選擇，每臺儀表可配用4種不同分度號的熱電偶(B、S、R、D或B、S、R、K)。9·儀表機殼為封閉式結構，可在工業現場的惡劣環境條件下長期可靠運行。接通電源后，熱電偶輸入端開路時，儀表處于時鐘顯示狀態。接通熱電偶后，預備燈亮（綠燈）儀表脫離時鐘顯示狀態進入預備狀態，屏幕顯示輸入端溫度（冷端溫度），當熱電偶插入金屬熔液1～2秒后，黃燈亮，儀表進入測量狀態，計算機自動尋找溫度平臺。找到平衡點后紅燈亮，電聲器響，表示測量結束，并提醒操作者提槍。微處理器對采樣數據進行處理后送LED顯示器顯示，帶有打印機的儀表打印機自動打印本次測量的時間及結果，同時數據送往BCD碼接口或4～20mA(或1～5V)模擬輸出接口，測量過程結束。儀表顯示值將一直保持到下次更換熱電偶時被新的輸入端溫度所代替，在沒有更換新偶頭前，即使舊偶頭被拔掉或偶絲開路顯示溫度值仍保持不變。如果進入測量狀態后，儀表在規定的時間內沒有找到溫度平臺或在測量過程中偶絲開路，以及測量尚未完成前操作者提早拔槍都將導致本次測量失敗，紅燈亮，電聲器響后儀表顯示“ －"此時微處理器對儀表打印口，BCD碼輸出口，模擬量輸出口均不操作。SCW-98系列測溫儀是以微處理器8031為核心的智能測溫儀表，信號經模擬開關送至A/D轉換器，其中一路由感溫元件AD590把從儀表輸入端來的溫度信號（0～50℃）轉換成電信號送至A/D轉換作為熱電偶冷端補償，另一路由熱電偶mV信號經前置放大器處理后送至A/D轉換，模數轉換采用12位雙積分式A/D轉換器ICL7109，采樣速率為每秒12.5次，每次轉換時間80mS為工頻周期的整倍數，根據香農采樣定理該A/D轉換器有良好的抑制工頻及高次諧波干擾的能力。儀表在設計上采用了由微處理器控制的自動校準電路，在每次接通新熱電偶時，對儀表模擬電路部分進行零點及放大倍數的校準，測得此時儀表的漂移量并將其存入微處理器的RAM中，以便在測溫時將漂移量扣除，從而消除了儀表硬件所產生的時漂溫漂，提高了儀表的精度及穩定性，
