RELATIVE: Pushbutton allows zeroing of on range readings. Allows readings to be made with respect to baseline value. Front panel annunciator indicates REL mode. DATA LOGGER and MIN/MAX: 100 reading storage capacity; records data at one of six selectable rates from 3 readings/second to 1 read- ing/hour or by manual triggering. Also detects and stores maximum and minimum readings continuously while in data logger mode. CONVERSION RATE: 3 readings/second. OVERRANGE INDICATION: “OL” displayed.
