INSTRUMENT DESCRIPTION
1.3
Description of Equipment
Physical: The circuitry is enclosed in a rugged bench top
case.
Dimensions: 101 mm (4”) x 292 mm (11.5”) x 203 mm (8”).
Weight is 1.6 kg (3.6 lb). Controls and connectors are of a
size and spacing such that the instrument may be operated
while wearing safety gloves.
Electrical: The R1L-B is powered by an internal battery
consisting of three rechargeable NiCad ‘C’ cells (3000 mAh)
with a built-in charger. Input power for the charger is 90 to
250 VAC at 50 Hz or 60 Hz. Charging power is supplied via a
removable line cord; one end of which plugs into a line filter on
the front of the R1L-B, and the other end being a standard
three-pin grounded line plug.
Input Protection: The R1L-B will not be damaged by a signal
of 1 Vp-p applied across any pair of input terminals.
Environmental: This unit will operate over a temperature
range from 0 °C to 50 °C, 75% RH non-condensing, up to
3050 m altitude.
