i. Data Hold
Press the
HOLD
button at any time on any function
to freeze the reading on the LCD display. This
function is very useful when measuring in locations
where the display is difficult to read.
j. Trim
(Average sensing mode for ACV, ACA, OHM, Diode
and Continuity.)
Press the
TRIM
button when measuring unstable
signals to stabilize the reading. The 296 will aver-
age the measured value approximately every 1.25
seconds to obtain a clearer picture of the current
or voltage being measured.
k. Peak Mode
1.
Set the 296 to the
ACA
function.
2.
Push the
RNG
button and select the desired
measurement range.
3.
Push the
TRIM
button until PEAK shows on LCD.
4.
Allow the LCD to stabilize to zero.
5.
Clamp the jaws around a single conductor to the
device to be measured.
6.
Apply power to the device under test.
7.
Read the PEAK current on the LCD immediately
after the test.
h. Measuring Frequency
CAUTION!
Do not attempt to make frequency measurements with
test leads. The 296 measures the frequency by clamp-
ing the jaw around one conductor (wire). Clamping
around more than one wire will result in erroneous read-
ings.

Measurement Procedure:
1.
Disconnect power to circuit to be measured.
2.
Set the rotary switch to the
FREQ
function.
3.
Clamp the jaws around one conductor of the circuit
to be measured.
4.
Reconnect power to circuit to be measured.
5.
Read the frequency on the 296.
Note:
The current of the frequency being measured is
displayed on the bar graph.
Optional Modes:
•
HOLD:
Freezes the reading on the LCD.
•
RANGE:
Manually ranges the instrument.
