Figure 2-3. Adjusting Handle

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 Eis held down while the power-up sequence is in 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.

Pushbuttons can be used in three ways. You can:

•Press a single button to select a function or operation. EXAMPLE: Press Zto select volts ac for the primary display. Press a combination of buttons, one after the other.
