Do Not immerse in,
or expose to liquid or
dust.
No User-serviceable
components. Do Not
open unit, as it voids
warranty and
calibration.
Do Not drop, expose to
shock, or place heavy
objects on unit.
Do Not apply pressure
to display.
Avoid extremes of
temperature. Max
accuracy in 20-25
degree Celsius range.
DEVICE
USE AND CARE
Only use a clean,
dry cloth to clean
unit.
Do Not exceed
maximum device
load of 1.0A. Higher
current can cause
device failure.

BEFORE USE
If desired, remove the protective film from the front of
the NanoRanger unit. Peel carefully from below the
Positive
and Negative terminals. NanoRanger will
still function normally, if the film is left in place.
INSERT 2 x AA BATTERIES
1. Remove battery compartment cover (H) applying
gentle pressure to finger pad.
2. Ensure clean contacts on batteries.
3. Insert new batteries, observing polarity
instructions in battery compartment.
4. Replace battery compartment cover.
2 x AA alkaline batteries will give in excess of 150
hours of continuous operation. Treat all batteries in
accordance with the manufacturer’s instructions.

SCREEN GUIDE
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 which range
constraint has been input, via the menu. In this example, none.
C
- The Signal to Noise Ratio (SNR). The SNR indicates how much
noise, variation, and AC components are in the signal, followed by
Maximum and Minimum samples during the reading.
D
- Maximum (Mx) and
E
- Minimum (Mn). The Mx and Mn Readings
shown are those that have occurred since this measurement started.
Below that, the highest (Sh) and lowest (Sl) Samples are shown, from
which the Readings have been derived.
GETTING STARTED - TAKE A READING
WARNING
. Use
NanoRanger with
cables less than 3
metres in length.
STEP 1: POWER ON
After inserting batteries
as shown, press the
POWER button to start
NanoRanger.
Connect
Positive
terminal (
RED
) to
the higher voltage
side of the current
to be measured.
STEP 2: CONNECT LEADS
Connect Negative terminal (BLACK)
to the lower voltage side of the cur-
rent to be measured. Current
must
flow from
Positive
to Negative.
Leads (not supplied) should be
industry standard, uninsulated,
4mm banana plug. Leads of 0.3M
will help minimise any noise.
STEP 3: TAKE MEASUREMENTS
Sampling at a high rate to
eliminate mains noise, Nano-
Ranger takes about 3 readings
per second. It displays the current
in mA, uA, nA, and pA. In this
example, 0.309uA.
A Range Bar underneath the digits
shows which ranges are in use.
The Range Bar oscillates after
each reading to show how quickly
readings are occurring and to
provide a visual confirmation that
the device is functioning correctly.
STEP 4: POWER OFF
After measurements
are taken, press the
POWER button
again to return
NanoRanger to
Standby mode.
