Page 4: Preface
Preface The User NanoRanger is not a toy. It is a precision instrument and should be treated accordingly. It is aimed at the hobbyist, maker and professional User community. This Manual assumes a level of technical expertise on the User’s part. NanoRanger should not be used by those without a knowledge of safe working on electronics. -

(thousands of pounds), to cheaper solutions that only have limited manual ranges. The NanoRanger is a solution to these challenges, as it provides a 3.5-digit, 9 range ammeter that can switch over 8.5 decades (from 800mA to 1nA), with resolutions down to 10pA. It features: •... -
Page 6: Technical Data
Fast up-range switching is needed when a device under test comes out of standby mode. The NanoRanger can switch up a range in less than 30uS and change from the lowest to the highest range in approximately 200uS. -

Page 8: Understanding The User Interface
Understanding the User Interface A - The current reading, displayed in mA, uA, nA, and pA. In this example, 0.309uA. B - The small, lower Range Bar shows which ranges are in use. The upper, longer Range Coverage Bar shows movement across the ranges during the reading. The box surrounding both shows what range constraint has been input via the menu. - Page 9 Peel carefully from below the Positive and Negative terminals. NanoRanger will still function normally if the User chooses to leave the film in place. 2.7.3 Attach Feet (if desired) NanoRanger is supplied with 4 rubber feet, for Users requiring added stability. Attach these with due regard to the areas that will experience pressure during normal use;...

Page 10: Nanoranger Menu Structure
Controls Firstly, ensure batteries are fitted in accordance with 2.7.1 (above). Three buttons control the operation of the NanoRanger; Power, Menu, and Select. Pressing the Power button will start the NanoRanger. Two start-up screens will display whilst loading the code: One with the AltoNovus logo: The second with battery voltage*, software release (here ALT-1.11), NanoRanger serial number... - Page 11 • Measure Average. • Advanced. These Menu options may change in the future. NanoRanger software updates will be available from time to time. Register for notifications at info@altonovus.com. 2.8.1 Measure The Measure feature performs a measurement, as described in Section 4.
- Page 12 The following screen will then be displayed: • The average current is shown over the period. In this case, 31.1uA. • The sample time is shown in multiples of 200mS. In this case, 18.85 seconds. • The total charge for the period is shown. In this case, 162.410nAh. •...

Page 13: Safety
Safety CAUTION! NanoRanger is designed to measure low levels of current. Do not expose to excess load. Excess load can result in component failure. Using NanoRanger Safely 3.1.1 Environmental Conditions: • NanoRanger is not intrinsically hazardous. Users should take the same care when using NanoRanger as they would with any other device that measures live electric currents. -
Page 14: Guide To Graphical Symbols
3.1.5 Installation Safety Information: • NanoRanger is delivered ready for use. With temperature variation in transit, Users should allow the device to acclimatise to the operating environment before use. 3.1.6 Maintenance Safety Information: •... - Page 15 3.2.2 Explanation of Graphical Symbols in this Instruction Manual SYMBOL MEANING Do not immerse in, or expose to, liquid. Avoid extremes of temperature. Precision electronic instrument. Do not drop. Do not subject to heavy weights or excess pressure. No User-serviceable parts. Do not open unit.

Page 16: Taking Manual Readings
Power button will start the NanoRanger. Following start-up, NanoRanger will take 1073 samples to build up a reading over 200mS. This is undertaken to eliminate mains noise at both 50Hz and 60Hz and to give an accurate average over the period. -
Page 17: 4.3 Setting The Range Limit
4.3 Setting the Range Limit Via the Menu, it is possible to define the range across which NanoRanger will operate. The range bar underneath the digits shows which ranges are currently in use, moving left and right to confirm the range. -
Page 18: 4.6 Power Off
Commands / responses are terminated with a Line Feed. While NR-01 is USB enabled, the chip it uses converts output to Rs232. Set the baud rate to 57K6 on the port. AltoNovus uses Realterm as a terminal program. Again, set the port speed to 57K6. -
Page 19: Scpi Required Commands
5.3.2 Power Off (SYSTem:POWer) SYSTem:POWer This command will turn the NanoRanger off, similar to the power button on the front panel. 5.3.3 LCD Backlight (CONFigure:LED) CONFigure:LED <0,1> This command will turn the LCD backlight LED On or Off. 0 = off, 1= On. For example: CONFigure:LED 0 This command turns the backlight LED Off. - Page 20 Range Settings (CONFigure:RANge) CONFigure:RANge <0..8> This command sets the range of the NanoRanger. There are 9 ranges, as detailed below. Do Not subject the NanoRanger to currents above the selected range, as this may damage the device: 0 = 20.00nA 1 = 200.0nA...
- Page 21 CONFigure:RANge:MAXimum? This command returns the current maximum range setting of the NanoRanger. CONFigure:RANge:MINimum <0..8> This command sets the minimum range of the NanoRanger. On Powerup, or *RST the maximum range will be 0. CONFigure:RANge:MINimum? This command returns the current minimum range setting of the NanoRanger.
- Page 22 +3.1E-06,+2.71E-09<CR><LF> Maximum sample 3.1uA, minimum sample 2.71nA. 5.3.10 Reading (READ?, MEASure?, INITiate) READ? This command initiates a reading. It is the same as MEASure? and INITiate. For example: +3.1E-06<CR><LF> Measurement is 3.1uA. 5.3.11 Triggering (TRIGger:COUnt) TRIGger:COUnt This command sets the number of triggers for a measurement. Each measurement takes 200mS.
