OM 10 data sheet

The OM10 micro ohmmeter is used for four wire impedance measurement, with excellent accuracy ranging from low values (resolution of 10 μ W) up to 50KW. It includes thermoelectric compensation and temperature compensation. It can also measure DC and AC voltage and ambient temperature.

application…………………………………..
On site, workshop or laboratory, the main applications are as follows:

1. Measurement of cable impedance and resistivity
2. Inductive impedance measurement (for motors, transformers, etc.)
3. Contact resistance measurement (quality of connectors, switches, relays, contacts...)
4. Metal coating and grounding measurement
5. Testing and measurement of electrical components: resistors, fuses, electric heating regulators, heating elements, PCB exchanges, etc
6. Surface condition, impedance of mechanical bonding, and material testing.

Display of measured values in units and ambient temperature.
Display: Measurement range, current type, possible temperature compensation.
50000 counts (4 1/2 digits digits) LCD 13 mm high (0.5 ")
The selection of range, current waveform, temperature compensation, and trigger can be made through the keyboard.
Four line measurement with automatic compensation is used for temperature difference electromotive force (EMF) and automatic environmental temperature compensation.

measuring current…………………………………..
Users can choose two waveforms of current:
-Continuous (DC/DC) for inductive impedance measurement (constant current)
-Pulse, in other cases: the current stops between measurements (advantage: low heating impedance during testing and low consumption)

Time…………………………………..
In DC direct current: 0.5 s,
In pulsed pulses: 1 s.

Protectionprotect…………………………………..

1. Electronic protection can reach 250V at input (430V at voltage measurement)
2. Electronic protection prevents interruption of current when measuring an inductive impedance.

calibration…………………………………..
For calibration, there is no need to turn on the instrument, just connect a standard resistor and add its value through the keyboard.

condition…………………………………..
Nominal operating temperature and humidity: 0 to+50 ° C, 20 to 75% RH
Maximum operating temperature and humidity: -10 to+55 ° C, 10 to 80% RH
Maximum storage and transportation temperature: -30 to+60 ° C
Protection according to IP41

power supply…………………………………..
Internal battery pack Ni Cd: 1.7 AH
Battery life (typical use)>10 hours. An external main charger, delivered as standard with the instrument. It allows for either battery charging or fixed use of mains power.

introduce…………………………………..
Durable ABS plastic casing for on-site or workbench use.
Size: 120 x 65 x 245 mm.
Weight: 1.1 kg.
When delivering, use a carrying transport box and a mains power adapter.

function
resistance measurement…………………………………..
From very low values (resolution 10 μ W) to 50KW, use:
Measurement and automatic compensation for thermoelectric force measurement (electromotive force)
Measurement and compensation (user selected) of ambient temperature
With temperature compensation, OM10 displays the theoretical resistance value of copper or aluminum at 20 ° C (other metals depending on demand). The measurement of ambient temperature is carried out using a sensor embedded in the instrument and displaying it.
