Two-Point Calibration Procedure

The Johnson 1435-1000D is a digital torpedo level designed for reliable operation in various jobsite conditions. It features a robust construction, a backlit LCD for clear visibility, and an IP65 rating, making it dustproof and waterproof. The level incorporates strong rare earth magnets and a V-groove top edge for secure attachment to ferrous surfaces and pipes.

Function Description:

The primary function of the Johnson 1435-1000D is to measure and display angles in various units. It can show measurements in degrees, percent, inches per foot (in/ft), and millimeters per meter (mm/m). The main display shows the current angle, while a sub-display can be used to store hold values or target values, which is useful for inspection checks and working in tight spaces.

The level offers preprogrammed 22.5° and 45° modes, simplifying common tasks like miter cuts and conduit bends. Users can also set custom angles to replace these modes. An audible indicator can be toggled between high, low, or off volume settings. The backlight has two stages (low and high) and automatically times out after approximately 20 seconds in a stationary position to conserve battery life. Moving the level slightly reactivates the backlight.

Important Technical Specifications:

Accuracy: ±0.1° at 0°/90°; ±0.2° for other angles.
Battery: 1 x CR2032, providing up to 16 hours of operation.
Units: Degree, Percent, in/ft, mm/m.
Backlight: Two-stage with timer.
Operating Temperature: 14°F - 122°F (-10°C - 50°C).
Weight/Dimensions/IP Rating: 8 oz, 10" x 2" x 3/4", IP65.

Usage Features:

Power On/Off: Press the POWER button to turn on. Hold the POWER button to turn off.
Calibration: The device supports a two-point calibration process. With the power off, hold POWER until "CAL 1" appears. Position the level upright with the LCD facing you and press POWER to store the first point. Rotate the level 180° (still upright, LCD facing away) and press POWER again to store the second point. Calibration is then complete. An alternate single-point calibration can be performed by leveling the torpedo using the vial and holding POWER and HOLD while the power is off.
Unit Selection: Press the UNIT button to cycle through degrees, percent, in/ft, mm/m, 22.5°, and 45° modes.
Custom Angle Setpoints: In 22.5° or 45° mode, hold UNIT to enter custom setpoint mode. The sub-display digits will flash, indicating they can be changed. Use HOLD to change the active digit and UNIT to advance to the next digit. The new value is stored automatically.
Hold Mode: Press HOLD to enable hold mode, which freezes the current measurement on the display. Press HOLD again to transfer the held measurement to the sub-display.
Volume Control: Hold HOLD to toggle the volume between high, low, and off.
Backlight Control: While powered on, press POWER to enable the backlight (low setting). Press POWER again to switch to high backlight.
Factory Reset: If needed, a factory reset can be performed by holding HOLD, UNIT, and POWER simultaneously for 10 seconds.

Maintenance Features:

Battery Replacement: The level uses one CR2032 battery. To replace, remove the battery door by rotating the retaining screw counterclockwise with a #2 Phillips screwdriver. Insert the new battery positive side up and replace the door, gently tightening the screw.
Troubleshooting:
- If the tool does not power on or remain on, replace batteries and check polarity.
- If the display is frozen, ensure hold mode is not enabled by pressing HOLD once or twice.
- If the level is not reading correctly, perform a calibration.
- If the backlight does not stay lit, move the level slightly to reactivate it, as it times out after 20 seconds of inactivity.
