Triplett 9045 - Manual (Page 18)

18 Triplett Model 9045
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.
On the position of the rotary FUNCTION switch, use the
SELECT button to choose the desired measurement mode.
To determine the measurement mode, observe the LCD display annuncia-
tors while the SELECT button is being pressed.
7.1.4 Using the Backlite
The LCD incorporates a blue LED backlite that aids the user when using the
meter in poorly lit areas. The same button that activates the HOLD is used to
activate the Backlite. To turn on the Backlite, the
button is pressed
and held for 2 seconds or longer. Because the Backlite consumes so much
power (it uses more power than all of the other electronics in the meter), it
only stays on briefly (about 8 to 10 seconds) and automatically turns itself
off. To turn the Backlite off manually, before it goes off automatically, press
and hold the button again until the Backlite turns off.
Since the HOLD feature and Backlite feature share the same button, there is
some interaction in their operation. A few presses of the button will reveal
how to use the button effectively.
