Operation
4.1. Voltage Ranges
Suggested operation procedure is as follows:
Select Off position on output switch.
Turn on, and select required range.
Check battery level indicator for high enough reading (see ‘Battery Replacement’).
Select required output on the ten turn potentiometer, which can then be locked by
pushing the lever at the bottom to the left. The ten turn potentiometer linearly adjusts
the output from zero to full scale on any range. The number of complete turns is
displayed in the dials window, parts of a turn are red on the inner scale, (calibrated 0-9
with 100 divisions), using the red indent as a pointer.
EXAMPLE: To set 56.2mV:
1) Select 100 mV range.
2) Turn dial until 5 appears in the centre of the window.
3) Set inner scale to 6.2.
The table below shows the effect of the dial on each range.

Voltage Output.
1V 100 mV 10 mV 1 mV
100 mV 10 mV 1 mV 100uV
10 mV 1 mV 100uV 10uV
Current Output
100 mA 10 mA 1 mA 100 uA
10 mA 1 mA 100 uA 10 uA
NOTE:
0.001V = 1mV = 1000uV
0.001A = 1mA = 1000uA
5) Switch output to Normal or Reverse as required.
4.2. Output Voltages above 1V
To use the 8V range, connect the supplied 1K ohm resistor across the output
terminals, and switch to the 10mA range. The 1030 will act as a voltage source, the
output being adjusted with the 10 turn dial, with a scale of 1 volt per turn up to a
maximum of about 8 volts with a good battery.
This allows the output to be set between 0V and ±8V with a 10mV resolution and an
accuracy of 0.3% of full scale.
