116 Users Manual Using the Bargraph The bar graph is like the needle on an analog meter. It has an overload indicator (>) to the right and a polarity indicator (+) to the left. Because the bar graph updates much faster than the digital display, the bar graph is useful for making peak and null adjustments. The bar graph is disabled when measuring capacitance and temperature. In frequency, the bar graph and range annunciator indicates the underlying voltage up to 1 kHz. The number of segments indicates the measured value and is relative to the full-scale value of the selected range. In the 60 V range, for example (see below), the major divisions on the scale represent 0, 15, 30, 45, and 60 V. An input of −30 V turns on the negative sign and the segments up to the middle of the scale. Maintenance Maintenance of the Meter consists of replacing the battery and cleaning the case.
