RESISTOR
200mV and
To measure voltages above the meters basic sensitivity, attenuator
resistors R17 and R18 need to be installed. The general equation to
determine their values is given by: V
Where V is the input voltage required and V is the corresponding
display voltage. Note, V max is actually 199.9mV for a nominal
200mV basic sensitivity meter and 1.999V for a nominal 2V meter
Examples
For standard input ranges choose the corresponding resistors from
the range specification table below.
For inputs greater than 200V, R17 must be a high voltage resistor
such as Philips VR37 Series (1x2M2, 0.5W, RS164-8316) with
R18=2k2 Alternatively, use two carbon film resistors in series, such as
Multicomp MCF (2x1M2, 0.5W, Farnell 262-195) with R18 as 2K4.
See the options for R17 below. The maximum input voltage on this
range with correct resistors is 650V.
For ranges of 200V or less, for R17, use metal film resistors, 1%, 0.5W
as Farnell 545-314. For basic 200mV use only existing link JP1
For R18, on all voltage ranges, use metal film resistors, 1%, 0.25W
On current ranges, use metal film resistors, 0.5W for R30. The current,
using internal shunt resistor R30 must not exceed 2 Amps. Leave link
JP1 in place
The power supply input protection fuse is a 20mm cartridge type rated
at 250V / 100mA.
