Oilfield pumping unit tester

The ETCR 4800 is a dedicated multimeter for oilfield pumping units. It measures AC current up to 300 A and AC voltage up to 700 V simultaneously. Phase angle, make-break resistance and stroke parameters are captured in one instrument. A 240 × 160 dot LCD shows all readings at once.

Electrical maintenance teams.

This tool suits technicians who monitor pumping-unit health in petroleum fields. It covers current, voltage, frequency, phase, resistance and stroke timing in a single handheld unit. Buyers needing insulation resistance, power quality harmonics or three-phase power analysis should look at specialised analysers instead.

35 mm × 40 mm CT aperture

The current transformer opening measures 35 mm by 40 mm, setting the maximum conductor size that can be clamped. If the service cable exceeds this window, the meter cannot make contact. Verify the cable diameter against the aperture before purchase.

Questions about this item

How do I confirm the ETCR 4800 is measuring correctly after I connect the CT clamp?

The 240×160-dot LCD shows live AC current up to 300 A, voltage up to 700 V, frequency between 10 Hz and 70 Hz, phase angle from 0.0° to 360.0°, make-break resistance from 0.00 kΩ to 20.0 kΩ, plus stroke current peaks, ratio, timing and strokes per minute — all on one screen so you can verify the pumping unit instantly.

What ships in the box and what must I source separately?

The set includes the multimeter, a 35 mm × 40 mm CT clamp, a rechargeable Ni-MH battery already fitted, a mains charger and a USB cable for the 1 000-record data download; no extra sensors or leads are required for the listed measurements.

Which measurement ranges should guide my choice of this tester?

Select the 4800 when you need simultaneous AC current 0.0 mA–300 A, AC voltage 0 V–700 V, frequency 10 Hz–70 Hz, phase 0.0°–360.0°, make-break resistance 0.00 kΩ–20.0 kΩ and pumping-unit stroke analysis (peak up/down current, stroke ratio, stroke time, strokes per minute) all in one handheld unit.
