Manual Ranging
The meter powers on in the autoranging mode. Press the Range key to
go to manual ranging. Each press of the range key will step to the next
range as indicated by the units and decimal point location. Press and
hold the Range key for one second to return to autoranging.
Data Hold
Press the Data Hold key to freeze the reading in the display. "HOLD"
will appear in the LCD. Press the key again to release the display.
Relative Measurements
The relative measurement feature allows you to make measurements
relative to a stored reference value. A reference voltage, current, etc.
can be stored and measurements made in comparison to that value.
The displayed value is the difference between the reference value and
the measured value.
1. Perform any measurement as described in the operating
instructions.
2. Press the Relative button to store the reading in the display and
the "REL" indicator will appear on the display.
3. The display will now indicate the difference between the stored
value and the measured value.
4. Press the Relative button to return to normal operation.
Auto Off
The auto off feature will turn the meter off after 15 minutes of inactivity
(Range switch or a key has not been turned or pressed). A beep will
warn the user shortly before the auto off feature activates.
