OPERATING INSTRUCTIONS
The R1L-B is designed for bench-top operation. Use the
cables connecting their banana plug terminations to the four
binding posts I, +E, -E, and -I.
3.1 Rotary Switch Functions
Operation of the Model R1L-B is extremely simple. There are
only two switches.
The RANGE rotary switch manually scrolls through the five
ranges.
Full scale on any range may be described as 2,000 (actually
1,999), since this is a 3½ digit meter. If the readings are
exceeding 1,999 counts, step to the next higher range. If the
readings are less than 2,000 counts, step down a range, so
that it will read 1,999 counts, or less. The decimal point is
located automatically for the correct reading.
If the selected range is too low for the value of the resistor
under test, the display will show over-range.
The POWER rotary switch turns on the power to operate the
unit or turns off the power to the unit. The appearance of the
display will show that power is on; absence of the display
indicates that either power is off, batteries are discharged, or
there is some malfunction. Note that when power is turned
off, it may take several seconds to discharge circuit capacity
to completely blank the display. The black markings seen
have no effect and disappear when power is turned back on.
