AutoHOLD
Mode 
XWWarning 
To prevent possible electric shock, fire, 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. 
•  Do not use the HOLD function to 
measure unknown potentials. When 
HOLD is turned on, the display does not 
change when a different potential is 
measured. 
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 
. 
Relative Mode 
Selecting relative mode () 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 . Press 
 again 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.
