interface to set the resistance, and then enable the channel input.
:SOUR:RES:RANG 15
/*Sets the resistance range of the electronic
to a low range (0.08 Ω to 15 Ω).*/
:SOUR:RES:LEV:IMM
0.125
/*Sets the resistance value of the electronic
load to 0.125 Ω.*/
:SOUR:INP:STAT 1
/*Enables the channel input.*/
b) Turn on the digital multimeter. Select the DC voltage (DCV)
measurement function and set the range to "Auto". Make sure that the
electronic load works in CR mode. Read the digital multimeter and
record the reading (U
1
and U
2
) of the digital multimeter. Wherein, U
1
is
the input voltage of the electronic load, and U
2
is the voltage of the
current sampling resistance. Calculate the resistance of the electronic
load according to the formula: R

= U
1
/(U
2
/R
M
).
c) Calculate the CR programming accuracy |R
1
- R
L
|. Compare it with the
specified specifications in Table 2-12. Wherein, R
L
is the low resistance
value.
(2) Measure the CR programming accuracy when the resistance is set to a high
value.
a) Power on DL3031A. Send the following commands via the remote
interface to set the resistance, and then enable the channel input.
:SOUR:RES:RANG 15
/*Sets the resistance range of the electronic
load to a low range (0.08 Ω to 15 Ω).*/
:SOUR:RES:LEV:IMM

/*Sets the resistance value of the electronic
load to 15 Ω.*/
:SOUR:INP:STAT 1
/*Enables the channel input.*/
b) Turn on the digital multimeter. Select the DC voltage (DCV)
measurement function and set the range to "Auto". Make sure that the
electronic load works in CR mode. Read the digital multimeter and
record the reading (U
3
and U
4
) of the digital multimeter. Wherein, U
3
is
the input voltage of the electronic load, and U
4
is the voltage of the
current sampling resistance. Calculate the resistance of the electronic
load according to the formula: R
2
= U
3
/(U
4
/R
M
).
c) Calculate the CR programming accuracy |R
2
- R
H
|. Compare it with the
specified specifications in Table 2-12. Wherein, R
H
is the high
resistance value.
6. Measure the CR programming accuracy when the resistance range is a high
range (2 Ω to 15 kΩ).
