914X Field Metrology Wells
Parts and Controls
Block Temperature Indicator (10) [Patent Pending]
The Block Temperature Indicator lamp allows users to know when the block temperature is
safe (50°C to 60°C) to remove inserts or move the Field Metrology Well. The indicator light is
lit continuously once the block has exceeded approximately 50°C (varies 50°C to 60°C). The
indicator light stays lit until the block cools to less than approximately 50°C. If the instrument
is disconnected from mains power, the indicator light flashes until the block temperature is less
than approximately 50°C.
