Power-Up Configuration

The last number entered (or, in REL, the last measured value) is shown with the left most digit displayed in normal intensity and the remaining digits dim. (If the number is negative, the minus sign is dim.) Related annunciators are lit, and "EDIT" is shown in the secondary display.

2.Press Uto step the bright digit through numbers between O and 9. Holding down U causes this digit to scroll continuously.

Press Tto select the digit to be edited. Each press of Tcauses the digit to the right to be selected and go bright, while causing the previously selected digit to go dim. When the right most digit has been selected, the next press of Tselects the sign: if the sign is positive, the negative annunciator flashes bright dim; if the sign is negative, the negative annunciator is bright. Uwill toggle the sign between positive and negative.

3.Any time during editing, you can store a selected value by pressing E.

4.To abort the edit and return the meter to normal operation, press any button except E, U, and T.

Power-Up Configuration

Factory Settings of Power-Up Configuration

When the meter is turned on and completes the power-up sequence, it assumes its power- up configuration. The power-up configuration set at the factory is shown in Table 3-13.

The IEEE-488 address, the RS-232 baud rate, parity, echo, and print-only rate are not changed when power is cycled off and on. These parameters remain as set until changed by the user.

Changing the Power-Up Configuration

You can change the power-up configuration to one that more closely meets your needs and preferences. Any combination of meter parameters can become the power-up configuration.

To save any configuration in which the meter is operating, press Sand, while holding it down, press E. The following parameters are saved:
