Using the Bar Graph 
The bar graph is like the needle on an analog Meter. There is an 
overload indicator (►) to the right, and a polarity indicator (±) to 
the left.  
Because the bar graph is much faster than the digital display, the 
bar graph is useful for making peak and null adjustments, and for 
observing rapidly changing inputs. 
The bar graph is disabled when measuring capacitance. In 
frequency, the bar graph accurately indicates the voltage or 
current up to 1 kHz. 
The number of lit segments indicates the measured value and is 
relative to the full-scale value of the selected range. 
For example, in the 60 V range (see below), the major divisions on 
the scale represent 0, 15, 30, 45, and 60 V. An input of −30 V 
lights the negative sign and the segments up to the middle of the 
scale.

Cleaning  
Wipe the case with a damp cloth and mild detergent. Do not use 
abrasives or solvents. Dirt or moisture in the terminals can affect 
readings.  
Testing the Fuses 
XWWarning 
To avoid electrical shock or injury, remove the test 
leads and any input signals before replacing the fuse.
