The CAL-6B features six independent timing channels, each represented by a dedicated window and button.

Multi-Tasking: Users can track six different dishes or tasks at once, ensuring efficiency in busy restaurant or catering settings.

Time Range & Modes: It supports a timing range from 1 minute to 99 hours. Operators can switch between Hour:Minute (HM) and Minute:Second (MS) modes by long-pressing the increase button while connected to power until "NS" appears, then selecting the desired mode.

Memory Feature: The device includes a memory function that retains time settings even if the unit is powered off, preventing the need for repetitive reprogramming. User Interface and Controls

According to the YOOYIST operating instructions and similar 8-channel model manuals , the interface is designed for high scannability:

Time Setting: To set an alarm, press the time button, select a channel, and use the increase/decrease buttons to adjust the duration.

Alerts: Once the countdown reaches zero, a high-decibel alarm triggers. The volume is adjustable to remain audible over kitchen noise.

Display: Large LED digits provide a clear view of remaining time from a distance. Physical Build & Installation Designed for durability, the is constructed with a heavy-duty stainless steel frame.

It is important to clarify the name first, as "Calculagraph" is a specific term often associated with antique time-recording devices, while "CAL6B" is a standard model number for modern Digital Panel Meters used in industrial settings. The most common device bearing the "CAL6B" model number is a Digital Tachometer / Counter manufactured by companies like YALONG or similar industrial electronics brands.

Here is a feature breakdown and manual guide for the CAL6B Series Digital Tachometer/Counter, which is the most likely device you are inquiring about.

4. Installation and Setup

4.1 Unpacking and Inspection

• Inspect for shipping damage.
• Verify included accessories: power adapter, paper roll, USB cable, foot-switch, quick-start guide.

4.2 Mounting and Placement

• Place on stable, vibration-free surface.
• Avoid direct sunlight and high humidity.

4.3 Powering Up

• Connect 12 V DC adapter; charge internal battery for 4–6 hours before first use.
• Press power button; display shows boot sequence and firmware version.

4.4 Loading Paper (for thermal print model) Inspect for shipping damage

• Open paper compartment.
• Insert thermal paper roll with heat-sensitive side facing printer head.
• Feed paper through the slot and close cover.
• Press Print to advance and trim.

4.5 Connecting External Inputs

• Foot-switch: TRS jack — tip = start/stop, ring = reset (or as labeled).
• External trigger: connect to opto-isolated input; configure trigger polarity in settings.

4.6 USB and Drivers

• Device enumerates as virtual COM (CDC) over USB.
• Drivers: modern OSes generally include necessary drivers; if not, install supplied driver package.
• Default baud: 115200, 8N1. Data protocol: simple CSV lines for each event (timestamp, event type, elapsed).

1. Wiring (Standard Pinout)

Always disconnect power before wiring.

• Power: Typically AC/DC 85-265V (Wide voltage) or specific DC 24V depending on the specific sub-version.
• Signal Input:
  • Usually connects to terminals marked IN+ and IN- or SIG.
  • For NPN sensors: Signal wire to Input, Ground to Common.
  • For PNP sensors: Signal wire to Input, ensure proper grounding.

5. Operating Modes and Procedures

5.1 Manual Mode

• Press Start to begin timing; press Stop to record elapsed time.
• Press Print to produce a timestamped line showing start, stop, and elapsed.

5.2 Interval Mode (automatic successive timing)

• Set interval length and maximum cycles via Mode selector.
• External sensor or foot-switch triggers start/stop; device logs each interval and prints summary after run.

5.3 Count-down Mode

• Enter target duration via front-panel numeric input or USB command.
• Press Start; device counts down and beeps at zero; optionally prints an event.

5.4 Auto Mode (event-driven logging)

• Device waits for external trigger; on trigger, stamps current time and starts internal timing sequence as configured.

5.5 Calibration and Time Setting

• Access settings menu to set date and time for printed timestamps.
• Use USB serial command "SETTIME YYYY-MM-DD HH:MM:SS" or front-panel menu.
• RTC calibrated at factory; user can perform fine calibration if precise synchronization is required using "CALIBRATE" routine (provided in Appendix B).

4. Advanced Graphing Features

Once you’re comfortable with basics, explore these features:

Parametric Equations

• Switch to MODE > Graphing Type > Parametric, then input equations like:
  • x1(t) = cos(t)
  • y1(t) = sin(t)

Polar Coordinates

• Change the graph type to Polar and input equations like r = 2 + 5sinθ.

Data Plots

• Input data into tables (STAT > Edit) and create scatter plots or histograms.

Zoom Tools

• Use ZOOM > Box to isolate specific areas of a graph. Try ZOOM > Trace for smooth scrolling.

Chapter 5: Where to find the "CAL6B Calculagraph Manual" (Digital & Physical)

Despite the rarity, hope is not lost. Here is where the remaining manuals hide:

1. NAWCC Library (National Association of Watch and Clock Collectors): They hold the original factory archives for the Calculagraph Company. Request Technical Bulletin 1948-B, Series 6.
2. Vintage Telephone Equipment Forums: CAL6B units were standard in Bell System offices. Search for "Western Electric Calculagraph manual" as a cross-reference.
3. EBay / Worthpoint: Search for "Calculagraph Instructions." They appear as 1-page mimeograph sheets sold for $50–$200.
4. The "Calculagraph.org" Archive: A fan-maintained repository (currently run by collectors in New Jersey) that has PDF scans of the CAL6A and CAL6C manuals. The CAL6B is functionally identical to the 6C except for the reset lever geometry.

Pro Tip: If you find a manual for the CAL6A, you can use 90% of it for the CAL6B. The difference is the "B" model has a hairspring regulator on the balance cock (visible through the back). The A model did not.

Sequence 1: Simple Timing

1. Start: Press the top pusher (F) . The sweep hand begins moving.
2. Stop: Press the top pusher (F) again. Read the elapsed minutes/seconds on the main dial.
3. Reset: Press the bottom pusher (G) . Note: Do not reset while the balance wheel is oscillating.

Chapter 2: Anatomy of the CAL6B Movement

To use the manual effectively, you must identify the parts. The CAL6B is a column-wheel driven, single-button chronograph with a printing mechanism.
