For over a century, the has been the silent timekeeper of industry. While modern workplaces rely on digital logs and biometric scanners, the Cal6B Calculagraph remains a mechanical marvel—a testament to precision engineering designed to calculate elapsed time with a simple pull of a lever.
Before plugging in your Cal6B, perform a visual inspection of the housing and power cord.
The Cal6B is a mechanical time-recording machine primarily used to calculate . Unlike a standard time clock that merely stamps the current time, the Calculagraph uses a unique internal gear system to print two or three "dials" on a card. By comparing the start position to the end position, the user can instantly see exactly how many hours and minutes have passed. Key Specifications: Drive: Synchronous motor (110-120V AC, 60Hz). Printing Method: Ribbon-based impact printing. cal6b calculagraph manual
Because these are mechanical machines, dust and old oil are the enemies. It gums up over time. Use a high-quality synthetic clock oil on pivot points.
To set the time, most models require you to open the hinged case (usually with a specific Calculagraph key). Use the manual adjustment knob on the movement assembly to align the printing wheels with the current time. 3. Operating Instructions For over a century, the has been the
Ensure the unit is on a level, vibration-free surface. Many Cal6B units were designed to be "flush-mounted" into a desk or switchboard.
Install a . Ensure the ribbon passes between the type wheels and the platen. Cleaning the Mechanism The Cal6B is a mechanical time-recording machine primarily
