QUICK START GUIDE (Rev 1.0 dated 10 MAR 22)
ALTONOVUS LTD. 37 OAST HOUSE CRESCENT, FARNHAM, SURREY,
Do Not immerse in,
or expose to liquid.
IP54 rated.
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.
A - Positive Terminal
B - Negative Terminal
C - Display Screen
D - On / Off Button
E - Menu Navigation
F - Select Button
G - Isolated USB Interface
H - Battery Compartment
BEFORE USE
If desired, remove the protective film from the front of
the ΩhmRanger-LCV. Peel carefully from below the
Positive and Negative terminals.
ΩhmRanger-LCV will still function normally if the film
is left in place.
INSERT 2 x AA BATTERIES
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.
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.

SCREEN GUIDE
A- The Resistance reading, displayed in MΩ, KΩ and Ω. In the example
above, 2.1MΩ.
B- A small, oscillating Range Bar shows which range is currently in use.
An upper, longer Range Coverage Bar shows any movement across the
ranges during the reading (in this case, none). The box surrounding
shows the operating range.
C- The Voltage being applied by ΩhmRanger-LCV at the Positive
terminal, in this case 206.7mV, to measure the resistance.
D- The active Range and the measured Current.
E- 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 Current samples during the reading. Higher resistances (lower
currents) are more susceptible to noise.
GETTING STARTED - TAKE A READING
WARNING. Use
ΩhmRanger-LCV
with cables less
than 3 metres.
STEP 1: POWER ON
After inserting batteries
as shown, press the
POWER button to start
ΩhmRanger-LCV.
STEP 2: CONNECT LEADS
Connect the Resistance to be
measured between the Positive
(RED) and Negative (BLACK)
terminals of the ΩhmRanger-LCV.
Leads (not supplied) should be
industry standard, uninsulated, 4mm
banana plug. Leads of shorter
length will help minimise any noise.
STEP 3: TAKE MEASUREMENTS
Sampling at a high rate to
eliminate mains noise, Ωhm-
Ranger-LCV takes about 2.5
readings per second. It displays
the current in MΩ, KΩ and Ω. In
this example, 2.1MΩ.
A Range Bar below the digits
shows which ranges are, and have
been in use. The Range Bar
oscillates after each reading to
show how quickly readings are
occurring and to show that the
device is functioning correctly.
STEP 4: POWER OFF
After measurements
are taken, press the
POWER button
again to return
ΩhmRanger-LCV
to Standby mode.
Minimum stimulus
applied is 206mV. Do
not expose unit to
currents over 800mA.

USING THE FULLY ISOLATED USB INTERFACE
ΩhmRanger-LCV’s micro-USB interface can be used to export
readings and to control the device via a PC (SCPI-format). The
USB interface cannot be used to power ΩhmRanger-LCV, as it is
isolated from the main circuitry to prevent interference. For help
connecting ΩhmRanger-LCV, see the guidance in our website’s
ΩhmRanger-LCV section. For SCPI instructions, please download

ΩHMRANGER-LCV - BASIC MENU FUNCTIONS
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the User is encouraged to try to correct the interference by one or more of
the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different that to
which the receiver is connected.
- Consult the dealer, or an experienced radio/TV technician for help.
