2 Features and Functions
• If the multimeter is configured to take the measurement using an 
aperture  integration time, pressing   or   during front panel 
measurement operations will display APERTURE on the the main display 
line and the current setting on the second display line (e.g. 101.005mSEC). 
You can then use the navigation keypad to change the aperture setting. 
Press   to save the setting. If you wish to keep the previous setting, 
press   and do not save the changes.
• If either the ac voltage or ac current measurement function is selected, 
pressing   or   during front panel measurement operations will 
increase or decrease the bandwidth setting, and briefly display the new 
setting on the second display line (e.g. if the setting was 20 HZ : MEDIUM, 
the display will show 3 HZ : SLOW when you press  ). Repeated use of 
 or will scroll through the selection of three bandwidth settings (3 
HZ : SLOW,  20 HZ : MEDIUM and 200 HZ : FAST).
• If the frequency/period measurement function is selected, pressing   
or   during front panel measurement operations will increase or 
decrease the gate time setting, and briefly display the new setting on 
the second display line (e.g. if the setting was 0.1 GATE TIME, the display 
will show 0.01 GATE TIME when you press  ). Repeated use of   or 
will scroll through the selection of gate time settings (0.001 GATE TIME, 0.01 
GATE TIME,  0.1 GATE TIME and 1 GATE TIME).
Front Panel Alphanumeric Character Entry
When you are in the menus for storing instrument states (see  “Multimeter 
State Storage” on page 51), data logging and advanced triggering, you may 
need to manually enter an alphanumeric character on the second display 
line.
• To enter a number or character, press   or   to select the displayed 
character (digit or letter) you wish to edit. The selected character will 
flash to indicate it can be edited. Use the   and   keys to modify a 
digit (from 0 to 9) or a letter (from A to Z).
• To quickly enter large numbers, you may press   to scroll over to the most 
significant digit allowed and/or add leading zeros, instead of 
incrementing the less significant digits up from zero. For non–zero 
floating–point entries, you may also press   to scroll to the magnitude 
prefix (e.g. u,  m,  k,  M), then use the   and   keys to change the 
numerical entry.
The left and right arrow annunciators on the second display line will 
indicate if there are editable characters left or right of the one selected.
