Turning The Meter On; Using The Pushbuttons - Fluke 45 User Manual

1. Viewing Position
3. Carrying Position
If you have not already done so, plug the line cord into the connector on the rear of the
meter. The meter will operate on any line voltage between 90 V ac and 264 V ac without
adjustment, and any frequency between 45 and 440 Hz. However, it is only warranted to
meet published specifications at 50/60 Hz.

Turning the Meter on

To turn the meter on, press in the green, POWER button located on the lower-right of the
front panel. If the meter is being operated under battery power and you turn the meter off,
you must wait five seconds before turning the meter back on. If you do not, the meter will
not power-up.
When the meter is turned on, the primary and secondary displays light for about 4
seconds while the instrument performs an internal self-test of its digital circuitry. These
tests check RAM, ROM, A/ D, calibration, and the display. The meter has passed all tests
and is ready for normal operation if an error code is not displayed. However, if an error is
detected, the meter will still attempt to operate. (Refer to "Self-Test Diagnostics and
Error Codes" in Chapter 6.)
If any front panel button other than
progress, the entire display stays on until another button is pressed. Then, the powerup
sequence continues.
After the meter completes the power-up sequence, it assumes the power-up measurement
configuration stored in non-volatile memory. The power-up configuration set at the
factory is shown in Table 3-13. (To change the power-up configuration, refer to
"Changing the Power-Up Configuration" in Chapter 3.)

Using the Pushbuttons

The pushbuttons on the front panel select meter functions and operations. A summary of
basic pushbutton operations is shown in Figure 2-4.
