Triplett Model 9045
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.
7.1.2 Auto Power Off
The 9045 has Defeatable Auto Power Off. This power saving feature auto-
matically turns the meter off 15 to 20 minutes after the last button press
or switch actuation.
The
annunciator appears on the LCD when the feature is activated. To
defeat the Auto Power Off, and keep the meter running continuously, hold
down the SELECT pushbutton while turning the meter on. The annunciator
will not appear in the display.
7.1.3 The SELECT Button
The 9045 has several test functions available on one position of the rotary
FUNCTION switch. To access the different functions, the SELECT button is
momentarily pressed, repeatedly if necessary, until the desired function is
obtained. In the Voltage and Current measurement modes, the SELECT
button allows either AC or DC signals to be measured. In the Temperature
measurement mode, the SELECT button allows the meter to display its
measurement in either Centigrade or Fahrenheit.
