Stepping and Scanning 9-7
Step/Scan configuration
Internal Stepping/Scanning
The settings for internal stepping and scanning are explained as follows:
Timer — The maximum timer interval is 99H:99M:99.999S (Hour:Minute:Second format).
Channel 1 Count — This specifies the number of measurements to be performed while on
Channel 1. Keep in mind that for each step/scan cycle, only one measurement is performed on
Channel 2. Channel 1 Count can be set from 1 to 1023.
Reading Count — This indicates the total number of measurements that will to be performed
for each step/scan cycle. For example, if Channel 1 Count is set to 3, the Reading Count will
initially set to 4 (the extra reading is for Channel 2). For each additional step/scan cycle, simply
add 4 to the Reading Count. Therefore, to perform three step/scan cycles, set the Reading Count
to 12. Reading Count can be set from 2 to 1024.
NOTES • If you change the Reading Count, it must be a multiple of the initial count val-
ue. For example, if the initial Reading Count is 3, you can change it to 6 (or
9, or 12, etc.). If you enter a non-multiple value, the instrument will select the
next lower value that is a multiple.
• Reading Count can be set to a value >1024 or INFinite, but only the first 1024
readings will be stored in the buffer.
Perform the following steps to configure internal stepping or scanning:
1. Press SHIFT and then CONFIG. Use the key to display the present SCANNING type
(INTernal or EXTernal).
2. Press the or key to display INT, and press ENTER.
3. The present state of the timer is displayed (OFF or ON). Press or to display the
desired timer state, and press ENTER.
4. If you turned the timer on, the timer interval will be displayed. Use the edit keys (, ,
, and ) to set the timer interval, and press ENTER.
5. The present Channel 1 Count (CH1 CNT) is displayed. Use the edit keys to set the
number of measurements for Channel 1, and press ENTER.
6. The Present Reading Count (RNG CNT) is displayed (it will be CH1 CNT + 1). If you
wish to increase the Reading Count, use the edit keys to display the value, and press
ENTER to return to the normal display state.
