AutoHOLD Mode XWWarning To avoid electrical shock or personal injury, do not use AutoHOLD mode to determine that circuits are without power. The AutoHOLD mode will not capture unstable or noisy readings. The AutoHOLD mode captures the present reading on the display. When a new, stable reading is detected, the Meter beeps and displays the new reading. To enter or exit AutoHOLD mode, press D. Relative Mode Selecting relative mode ( F) causes the Meter to zero the display and store the present reading as the reference for subsequent measurements. The Meter is locked into the range selected when you pressed F. Press Fagain to exit this mode. In relative mode, the reading shown is always the difference between the present reading and the stored reference value. For example, if the stored reference value is 15.00 V and the present reading is 14.10 V, the display shows -0.90 V. Multimeters AutoHOLD Mode Maintenance XWWarning To avoid electrical shock or personal injury, repairs or servicing not covered in this manual should be performed only by qualified personnel as described in the 80 Series V Service Information. General Maintenance Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Fuse Test If a test lead is plugged into the mA/μA or A terminal and the rotary switch is turned to a non-current function, the Meter chirps and flashes "LEAd" if the fuse associated with that current terminal is good. If the Meter does not chirp or flash "LEAd", the fuse is bad and must be replaced. XWWarning To avoid electrical shock or personal injury, remove the test leads and any input signals before replacing the battery or fuses. To prevent damage or injury, install ONLY specified replacement fuses with the amperage, voltage, and speed ratings shown in Replacement Parts in the Users Manual located on the 80 Series V User Manual CD. 13
