Using the Review Mode
Perform the procedure in Figure 2-18 to operate the Review Mode of operation. The
Review Mode is used any time during or after operation of the Scan Mode. While the
instrument is in the Scan Mode, the last, maximum, and measurements for each scanned
channel are stored in memory and updated with each scan, forming the Review Array.
For example, during scan operations, N can be used to monitor the maximum
measurement of a channel in real time. The Review Array is cleared by a control
sequence (see Figure 2-18 below), or by changing any parameter of any channel or the
measurement rate. The Review Array can be printed out using the L key (see Figure
5-4). If the instrument is in the Review Mode and scanning using the memory card, any
illegal memory card operations is noted only with a double "beep." If a double beep is
heard, exit the Review Mode and check the memory card error (see Figure 2-16).
