Using the +2 Hrs/-2 
Hrs buttons

The +2 Hrs and –2 Hrs buttons shift all three 
waveforms forward or backward by two hours without 
changing the time scale. If you press and hold the 

buttons, the time scale shifts every ½ second. If less than 2 hours of data 
exist, the waveform shifts by the amount of available data. The buttons are 
grayed if the waveform cannot shift any further. 

The Zoom button allows you to zoom in on trended data by 
switching the time scale to two hours, centered around the cursor 
position. If the current time scale is two hours, the zoom button is 
grayed.

When the Zoom button shows a magnifying glass with a plus (+) sign, the 
“zoom in” function is available. Once zoomed in, the button changes to a 
magnifying glass with a minus (-) sign to indicate that the “zoom out” function 
is available, and the Time and View buttons are disabled. Zooming out returns 
the waveforms to their previous time scale and all buttons to their previous 
states.

The Rescale button automatically adjusts the vertical axis for 
all three waveforms. The software determines a scale based on 
the minimum and maximum values of the data to display an 
optimal view.

Grayed-out 
button 
indicates that 
the time scale 
is not 
available
