Note:

• Range-Lock Feature: When a measurement reading is being displayed in

AutoTect

mode, press the RANGE button momentarily 1 time this locks the

function-range it is in. The symbol " Auto"disappears. Range-lock can speed

up repetitive measurements. Press the button momentarily repeatedly to

step through the ranges. Press and hold the button for 1 second or more to

resume AutoTect

• As Hazardous-Alert: When making resistance measurements in AutoTect

mode, an unexpected display of voltage readings alerts you that the object

under test is being energized.

• Ghost-voltage buster: Ghost-voltages are unwanted stray signals coupled

from adjacent hard signals, which confuse common multimeter voltage

measurements. Our AutoTect

impedance (approx. 1.6kΩ at low voltage) to drain ghost voltages leaving

mainly hard signal values on meter readings. It is an invaluable feature for

precise indication of hard signals, such as distinguishing between hot and

open wires (to ground) in electrical installation applications.

WARNING:

• AutoTect

mode input impedance increases abruptly from initial 1.6kΩ to

a few hundred kΩ's on high voltage hard signals. "LoZ" displays on the LCD

to remind the users of being in such low impedance mode. Peak initial load

current, while probing directly to 600VAC for example, can be up to 530mA

(600V x 1.414 / 1.6kΩ), decreasing abruptly to approx. 4mA (600V x 1.414 /

210kΩ) within a fraction of a second. Do not use AutoTect

that could be damaged by such low input impedance. Instead, use slide-switch

function selector common input impedance voltage modes (Hi-Z of approx.

5MΩ) to minimize loading for such circuits.

Manual or Auto-ranging

When the function selected has more than one range, press the RANGE button

momentarily selects manual-ranging. The meter remains in the range it was in.
