AutoHOLD Mode XWWarning To prevent electrical shock or personal injury, do not use AutoHOLD mode to see if circuits are without power. The AutoHOLD mode will not hold on unstable or noisy measurements. The AutoHOLD mode locks the current measurement on the display. When a new, stable measurement is sensed, the Product beeps and shows the new measurement. To start or exit AutoHOLD mode, push D. True-rms Digital Multimeter AutoHOLD Mode Relative Mode When you set relative mode (F),the Product zeros the display and stores the current measurement as the reference for subsequent measurements. The Product is locked into the range selected when you pushed F. Push F again to exit this mode. In relative mode, the measurement shown is always the difference between the current measurement and the stored reference value. For example, if the stored reference value is 15.00 V and the current measurement is 14.10 V, the display shows -0.90 V. 37

Warning
To prevent electrical shock or personal
injury, do not use AutoHOLD mode to see if
circuits are without power. The AutoHOLD
mode will not hold on unstable or noisy
measurements.
The AutoHOLD mode locks the current measurement on
the display. When a new, stable measurement is sensed,
the Product beeps and shows the new measurement. To
start or exit AutoHOLD mode, push
D
.
Relative Mode
When you set relative mode (
F
),the Product zeros
the display and stores the current measurement as the
reference for subsequent measurements. The Product is
locked into the range selected when you pushed
F
.
Push
F
again to exit this mode.
In relative mode, the measurement shown is always the
difference between the current measurement and the
stored reference value. For example, if the stored
reference value is 15.00 V and the current measurement
is 14.10 V, the display shows -0.90 V.
