Choosing the Load Range
The dynamic load tool is equipped with two load range
settings (High & Low) The high load range offers the ability
to load more power (Typically ~55 W total) and has a current
monitor resolution of 5 mV/A. The low load range has a
lower loading power ability (Typically ~12 W total), but has
a higher current monitor resolution of 25 mV/A. The low
load range setting allows for better accuracy when
monitoring low load conditions. It is important to enable
only one of the loading options at a time. If both options are
enabled then both drive circuits will operate. This will not
cause any damage to the DLT, however both banks will be
producing loads and both load current sense lines would
need to be monitored and their respective current
representation would need to be summed in some manner.
The two load ranges have separate load sense monitoring
points. These are located just below the DLT’s operation
selector switches.
ATTENTION:
Disabling the High or Low Load section does not fully
disconnect them. There will still be a low leakage
current from the disabled drive stage.

Supplying Operational Power to the DLT
The DLT is powered by an external power supply. It will
operate with an input supply of 10 V
−
18 Vdc. The typical
input needed would be a 12 V supply capable of supplying
> 600 mA. The input power is attached to the DLT in the
upper left hand corner via TPWR3 & TPWR4 or via the
optional Molex Connector (Molex part #39-29-3046).

Connecting the Function Generator
A 50
W
coax cable with EZ Clips can be used to attach the
function generator to the two pin connector on the DLT with
two ways to drive it:
1. By using an arbitrary waveform generator. Use the
Direct Drive two pin connector and select EXT
drive.
When using this drive option, the signal generator
can be set to provide a drive signal that is a replica
