Operating safely with battery power

For safe operation, the instrument chassis should always remain at earth ground potential.

WARNING:To avoid electric shock, always use the Tektronix-provided grounding cable when the oscilloscope is operating on battery power and not connected to the external power supply. The Tektronix-provided grounding cable is not for permanent usage.

Without a connection between the chassis and earth ground, you may receive a shock from exposed metal on the chassis if you connect an input to a hazardous voltage (>30 VRMS, >42 Vpk). To protect yourself against possible shock, attach the Tektronix-provided grounding cable.

The grounding cable is necessary to provide protective bonding between the oscilloscope and a dedicated earthing terminal, in accordance with the NEC, CEC, and local codes. Consider having a qualified electrician to approve the installation.

The grounding cable shall be connected before powering on the oscilloscope and before attaching the probes to any circuit. Connect the grounding cable from the ground lug terminal on the side panel of the instrument to a dedicated earthing terminal. Make sure the teeth of the alligator clip makes good electrical contact and is secured against slipping.

The alligator clip on the grounding cable must be connected to a dedicated earthing terminal, an earthing terminal bar, or identified equipment grounding points (a rack cabinet for example). Make sure you have a good electrical connection to an appropriate grounding device that is identified with a Protective Earth symbol, or the word GROUND/GND, or the color green (green ground screw/conductor). If none of these are present, assume the connection is not earthed.

Always verify that the grounding cable is making good electrical contact by using an ohmmeter or continuity meter between the dedicated earthing terminal and the ground lug terminal on the side panel of the oscilloscope. Verify again anytime the oscilloscope has been left unattended.

Make sure the dedicated earthing terminal is located in close proximity to the circuit under test. Keep the grounding cable clear of heat sources and mechanical hazards such as; sharp edges, screw threads, moving parts, and closing doors/covers. Inspect the cable, insulation, and terminal ends for damage before use. Do not use a damaged grounding cable. Contact Tektronix for a replacement.

If you choose not to attach the grounding cable, you are not protected against electric shock if you connect the oscilloscope to a hazardous voltage. You can still use the oscilloscope if you do not connect a signal greater than 30 VRMS (42 Vpk) to the probe tip, the BNC connector center, or the common lead. Make sure all probe common leads are connected to the same voltage.

WARNING:Hazardous voltages may exist in unexpected places due to faulty circuitry in the device under test.
CAUTION:When operating the instrument on battery power do not connect a grounded device, such as a printer or computer, to the oscilloscope unless the instrument grounding cable is connected to the earth ground.

Battery pack installation

Install the battery pack to the back of your instrument.

Before you begin

The battery pack must be empty during the installation procedure. After installation, insert one or two batteries into the battery pack before you turn on the instrument.
CAUTION:The battery interface connector is susceptible to Electrostatic Discharge (ESD). Use ESD precautions with installing or removing the battery pack.
WARNING:Before operating the instrument with the battery pack connected without an AC power source, always connect the ground cable.


  1. Remove cover from battery interface connector on the back of your instrument.
  2. Attach the battery interface cover to the cover slot in the middle of the battery pack.
    Use this slot to save the cover for the battery interface connector when the battery pack is installed.
  3. Align the connector on your battery pack with the battery interface connector on your instrument and connect the battery pack to your instrument.
    There is a hole on the opposite side of the connector on the instrument and a peg on the battery pack to help with alignment.
  4. Install the four provided screws into the corner screw mounts on the battery pack.
    CAUTION:The recommended torque is 3.6 N·m (32 inch-lbf). Failure to fully tighten the screws makes the battery pack more susceptible to fall damage.
    To remove the battery pack, reverse this procedure.

Rechargeable battery installation

The battery pack has 2 battery slots and supports hot swapping of the batteries during operation to extend the battery run time. The batteries are charged when the instrument is connected to an AC power source or charge each battery separately using the Tektronix external battery charger (TEKCHG-XX).


  1. Use your fingers to push on the battery door latch and open the door upward.
    The battery door is made to easily detach from the hinges. The battery pack will still operate with the door open or removed.
  2. Use the triangle alignment keys on top of the battery and battery pack slot to place the rechargeable battery into slot one or two.
    The pull tab will be on the opposite side of the alignment key. A latch secures the battery in place when inserted into the battery pack.
  3. Close and latch the battery pack door.

Instrument stand to battery pack installation

Mount your instrument to the provided stand in three configurations.

Before you begin

Align the stand with the four VESA screw mounts (closest to the label) on the back of the battery pack.


  1. Hand tighten the bottom two screws on the stand to the bottom two VESA screw mounts.
    The instrument is now secured to the stand straight up and down.
  2. Hand tighten the top two screws on the stand to the top two VESA screw mounts.
    The instrument is now secured to the stand at a fifteen degree angle.
  3. Turn the instrument upside-down and hand tighten the top two screws on the stand to the bottom two VESA screw mounts.
    The instrument is now secured to the stand at a seventy-five degree angle when the stand is laying flat.

Battery status

When the battery pack is installed and a battery is inserted, an icon and battery menu indicates the battery status.

The battery icon is displayed in the upper right corner of the screen. Double tapping the icon opens the battery menu. The battery menu indicates whether a battery has been inserted in slot 1 or 2, the battery serial number, a remaining charge percentage, and the battery time to full or empty.

A safety warning message automatically displays in the battery menu when an instrument is turned on with battery power only or when the power cord is removed from an instrument operating on battery power. You must tap the safety warning acknowledgement button to close the battery menu.

The following table and images describe the different icon states, Time to full, and Time to empty.

1The battery icon displays a power cord when connected to an AC power source. This indicates that the battery is charging in the battery pack.
2The battery icon and a warning symbol when operating on a battery power alone.
3The battery icon turns red when less than ten percent of the battery charge is remaining.
4Time to full displays the time it takes for the battery fully charge when connected to an AC power source.
5Time to empty displays the remaining time until the battery is empty. It is only displayed when operating on battery power alone.

When the batteries in the 2-BP battery pack on your instrument have a low battery charge and the power cord is not connected, the power button will blink twice and then your instrument will turn off.

When two batteries are inserted into the 2-BP battery pack, the battery with the lowest battery life will begin charging first. The battery with the higher battery life displays a long Time to Full when it is not actively charging. The two batteries actively charge at the same rate when they reach a similar battery life. When both batteries are actively charging the Time to Full display accurately.
