Product Usage Instructions
Device Use and Care
Ensure the following precautions are taken to maintain the device:
- Do not immerse in or expose to liquid.
- Avoid dropping, exposing to shock, or placing heavy objects on the unit.
- Avoid applying pressure to the display.
- Avoid extremes of temperature; maintain accuracy in the 20-25 degree Celsius range.
- Do not open the unit as it contains no user-serviceable components, and opening it voids warranty and calibration.
- Only clean the unit with a clean, dry cloth.
Battery Installation
- Remove the battery compartment cover by applying gentle pressure to the finger pad.
- Ensure clean contacts on batteries.
- Insert new batteries observing polarity instructions in the battery compartment.
- Replace the battery compartment cover.
Getting Started – Taking a Reading
Follow these steps to take a measurement:
- Power On: Turn on the device.
- Connect Leads: Connect the leads ensuring they are less than 3 meters in length.
- Take Measurements: Observe the resistance reading, range bar, active range, measured current, and signal-to-noise ratio (SNR).
- Power Off: Turn off the device after use.
Menu Navigation
To access the menu options, press the Menu button. Use the Navigate and Select
buttons to move through the menu. Options include:
- Measure
- Voltage
- Powerdown
- LCD Light
- 4 Beep Read

GETTING STARTED
TAKE A READING
-
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.
DEVICE USE AND CARE
BEFORE USE
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.
- Remove battery compartment cover (H) applying gentle pressure to finger pad.
- Ensure clean contacts on batteries.
- Insert new batteries, observing polarity instructions in battery compartment.
- Replace battery compartment cover.
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.
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.
BASIC MENU FUNCTIONS
Press the Menu button to exit measuring and enter the Menu mode. This screen
will appear. Use the Navigate and Select buttons to move through the Menu.
The options are:
- Measure
- Voltage
- Powerdown
- LCD Light
- 4 Beep Read
- Details
VOLTAGE – Use this Menu option to select the maximum stimulus voltage
that will be applied by ΩhmRanger-LCV®.
The options are available are:
- 380 mV (the default setting), or
- 206 mV
POWERDOWN – Use this function to set and configure the period of inactivity after which ΩhmRanger-LCV® will power down automatically.
- Off
- 30 Minutes
- 1 Hour (the default)
- 2 Hours
- 4 Hours

LCD LIGHT – Use this function to toggle the ΩhmRanger-LCV® screen backlight ON and OFF. Disabling the backlight will extend battery life.
4 BEEP READ – Use this function to take readings only when Resistance values are stable within selected tolerances. An audible prompt is given when this is achieved.
DETAILS – Will display the ΩhmRanger-LCV®’s unique serial number, calibration date and status, and software version.
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 the full OR-01 Instruction Manual at: www.altonovus.com.
