Measurement Resolution

Chapter 4 Features and Functions

General Measurement Configuration

Resolution is expressed in terms of number of digits the instrument can measure or display on the front panel. You can set the resolution to

4, 5, or 6 full digits, plus a “1⁄2” digit which can only be a “0” or “1”. To increase your measurement accuracy and improve noise rejection, select 61⁄2 digits. To increase your measurement speed, select 41⁄2 digits.

5 digits

“1⁄2” digit

9 ' &

This is the 10 Vdc range, 51⁄2 digits are displayed.

P9'&

This is the 100 mVdc range, 41⁄2 digits are displayed.

,2+0

This is the 100 ohm range, 61⁄2 digits are displayed.

•For temperature measurements taken from the remote interface, the resolution is fixed at 61⁄2 digits. From the front panel, you can set the resolution in terms of the number of digits displayed past the decimal point (Measure menu).

•For ac voltage measurements, the resolution is fixed at 61⁄2 digits. The only way to control the reading rate for ac measurements is by changing the channel delay (see page 88) or by setting the ac filter to the highest frequency limit (see page 114).
