Fluke 87V-MAX Product Manual - Page 22

For increased sensitivity, the analog pointer moves across the scale four times for each range. The pointer returns to 0 (wraps around) when the equivalent digital display reaches 1024, 2048, and 3072 counts. Select the next higher range if the pointer is too sensitive. The analog pointer indicates a value lower than the digital display (up to 2.5% of range). Examples on the 40V range are: Digital Display = 5.00V 15.00V 25.00V 35.00V Analog Pointer= 4.8 4.5 4.5 4.2 Wrap = First Second Third Fourth Indication = 4.8V 14.5V 24.5V 34.2V With stable inputs, use the digital display for the best sensitivity and precision. P 0 1 2 3 4 5 6 7 8 9 0 Analog Display Scale Scale for each 1000 counts in the digital display. Q ± Analog Display Polarity Indicates the polarity of the input except in the Frequency Counter mode, when it indicates the polarity of the trigger slope (edge). How to Use the Meter R 4000 Input Range Annunciator mV Displays 4, 40, 400, or 4,000 input range for volts, amps, or ohms, and 400 mV. S OL Overload Indication Displayed on digital display when input (or math calculation in REL mode) is too large to display. If you are taking duty cycle readings, OL is displayed if the input signal stays high or low. All segments are illuminated on analog display. Items 20-23 describe annunciators that indicate the mode or state in which the meter is operating: T AUTO Autorange Meter is in the autorange mode and will automatically select the range with the best resolution. Meter powers-on in autorange mode. In the autorange mode, the meter ranges up at 4096 counts and ranges down at 360. When the meter is in the Manual Range mode, the overrange arrow is displayed until you manually select a range appropriate for the input value. See item 9 for manual ranging. 15 MyFlukeStore Find QuaSlhitoypPforordFulucktespOrondliuncetsato:nline awt:ww.wGwlo. balTestSupply.com.com [email protected]
