Once the desired channel has been selected, push 'HI/LO' key. Pushing it once will show the high peak attained by the selected channel. Pushing it a second time will indicate the low process value (NOTE: The second push, to display valley, must be initiated before the display reverts to normal display mode). Before
displaying high peak, the display will read 'CH2 HI' (for Channel 2 High Peak). Similarly, for low peak the display will indicate 'CH2 LO' (for Channel2 Low Peak) before showing the value.
If an attempt is made to display the high or low peak of a channel which has been turned off (in CH Setup), the display will read 'CHx OFF' (x=channel #) to indicate the channel status.
Peaks can be reset to the present value of process (e.g. if channel 1 is reading 200 C, its peaks can be reset to 200). This will allow tracking the process from present temperature being read by the unit. To reset high peak, first select the
channel whose peak is desired to be reset (by pushing the CH. SEL key). Once the channel has been selected, push HI/LO key and keep it pushed. The display will read 'HI P' following which the value of high peak will be displayed. With HI/LO key still pushed, go on to push the RESET key. The display will read 'RESEt' and the unit will then take the present value of process on that channel and enter it as new high peak. To reset low peak, release HI/LO key (from high peak display mode) and push it again immediately
