CAUTIONS ON OPERATION
1. UNKNOWN (MEASUREMENT) TERMINALS
Do NOT apply DC voltage or current to the UNKNOWN terminals. Doing so will
damage the 4278A. Before you measure a capacitor, be sure the capacitor is fully
discharged.
2. MEMORY CARD
Use HP-specified memory cards containing 4278A-specific data only. If other memory
cards are used, the 4278A may be damaged. Non 4278A-specific data contained on a
memory card is not guaranteed, and data may be lost.
To insert a memory card into the MEMORY card slot, hold the memory card with the
label facing upward and with the contacts at the slot opening. Insert the card into the
slot until it "clicks" in place.
To remove a memory card from the 4278A, press the UNLOCK button and remove the
card.
Do NOT remove a memory card while LOADing or STORing data. Doing so may
damage the memory card and any data stored in the memory card may be lost.
Store memory cards in their furnished card cases when not in use. The card case
protects memory cards from contamination and electrostatic discharge. Also, store
memory cards under the following environmental conditions.
Storage. Temperature Range: -30°C to +70°C
Storage Humidity Range: 30% to 85% (@+50°C)
Do NOT shock or stress memory cards.
When storing or moving your 4278A, be sure the memory card slot is empty (no memo-
ry card inserted).
Do NOT touch the connector contact surface of a memory card and do NOT use
chemical liquids to clean the contacts.
