FUNCTION DESCRIPTION
3.1
General Functions
3.1.1
DATA HOLD mode
Data Hold mode makes the meter stop updating the display.
Enabling Data Hold function in autorange mode makes the
meter switch to Manual ranging mode, but the full-scale
range remains the same. Data Hold function can be
cancelled by changing the measurement mode, pressing
RANGE key, or push HOLD key again.
To enter and exit the Data Hold mode:
1. Press HOLD key (short press). Fixes the display on the
current value, "H"" is displayed.
2.
A second short press returns the meter to normal mode.
3.1.2
Manual ranging and Autorange mode
The Meter has both manual ranging and autorange
options.
In the autorange mode, the Meter selects the best range
for the input detected. This allows you to switch test
points without having to reset the range.
In the manual ranging mode, you select the range. This
allows you to override autorange and lock the meter in a
specific range.
The Meter defaults to the autorange mode in
measurement functions
!hat have more than one range.
When the Meter is in the autorange mode, AUTO is
displayed.
To enter and exit the manual range mode:
1.
Press RANGE key. The Meter enters the manual
ranging mode. AUTO turns off. Each presses of RANGE
key increments the range. When the highest range is
reached, the Meter wraps to the lowest range.
12
NOTE: If you manually change the measurement range afier
entering the Data Hold modes, the Meter exits this
mode.
2.
To exit the manual ranging mode, press and hold down
RANGE key for two seconds. The Meter returns to the
autorange mode and AUTO is displayed.
3.1.3

Measurement Functions
3.2.1
AC and DC Voltage measurement
I
A
To avoid electrical shock andor damage to the
I
instrument, do not attempt to take any voltage
measurement that might exceed
lWOVdc or
75OVac rms.
To avoid electrical shock
andor damage to the
instrument, do not apply more than
lOOOVdc or
750Vac rms between the common terminal and
the earth ground.
The polarity of ac (alternating current) voltage varies over
I
time; the polarity of dc (direct current) voltage is constant.
The Meter's DC voltage ranges are
400.0mV. 4.000V.
40.00V, 400.OV and 1000V
:
AC voltage ranges are
400.0mV ,4.000V, 40.00V, 400.OV and 750V.
(AC 400.0mV range only exists in manual ranging mode).
