Triplett Model 9045

The bargraph visually indicates how the input quantity compares with the mea-

surement range of the meter. For example, if the meter is set to the 6 Volt DC

range, and 3 volts is applied to the meter’s input, the bargraph would extend from

0 to 30, half the length of the bargraph, indicating that the measured quantity is 1/

2 of the range setting. This feature is often used for “nulling” or “peaking” adjust-

ments, which are easier to visualize on the bargraph, rather than examining the

numeric digital reading.

7: MEASUREMENT PROCEDURES

WARNING!!!

Do not use the meter when the low battery annunciator is displayed.

This may cause the meter to produce inaccurate readings,

and lead the user to believe that no hazard exists, when,

in fact, dangerous voltages or currents are present.

7.1 Pushbuttons and their Functions

7.1.1 Using the HOLD feature

The 9045 incorporates a convenient HOLD feature. This feature “freezes”

the reading in the LCD when the button is quickly pressed and

released. To release the HOLD, press the button again.

Note: The annunciator appears in the LCD when HOLD is activated.

WARNING!!!

The meter may not show the presence of dangerous potentials when HOLD is

activated. For example, if HOLD is applied when the meter is reading zero,

and 120VAC is subsequently applied, the meter will continue to read zero.

Failure to observe this precaution may result in damage to the meter

or injury to the user.
