Unlike the basic meters people use at home, industrial models are designed to be more accurate, much more durable, and meet strict safety standards CAT III 1000V.
They provide the detailed and exact readings needed to find and fix problems in complex equipment, such as motor drives, factory automation systems, electrical panels, and large machines.
Aside from safety, accuracy, The main focus of CEM DT-9987 is having the specific features needed for industrial work. like Low Pass filter, loZ, low ohm measurement, TrendCapture graphically display, etc.
The industrial multimeter is essential for electrical technicians, industrial maintenance engineers, automation specialists, and power system operators.
Safety:
IEC61010-1 CAT IV 600V / CAT III 1000V
UL, CSA, and TÜV listed for maximum safety and global compliance
Applications:
-- Motor and drive troubleshooting
-- Control panel maintenance
-- PLC system diagnostics
-- Transformer testing
-- Predictive maintenance
Motor and drive troubleshooting
Use an industrial multimeter to identify the root cause of these common issues:
- Motor Won't Start:Verify control and supply voltages; test winding integrity.
- Overheating:Measure phase balance and current draw; check for voltage fluctuations.
- Drive Tripping:Inspect DC bus and output phase voltages; monitor supply stability.
- Phase Imbalance:Note: Voltage imbalance greater than 2–3% drastically shortens motor lifespan.
PLC system diagnostics
In PLC systems, an industrial multimeter is essential for checking power supplies, verifying I/O signals, testing wiring, and confirming sensor outputs. It is one of the most fundamental tools used in automation maintenance and troubleshooting.
TrendCapture graphically display
TrendCapture shows you a quick graph of your logged data, so you can easily spot any issues.
Helps capture intermittent faults, analyze signal quality, and monitor trends over time without a separate recorder
True RMS, high accuracy
accurately measures AC voltage/current regardless of waveform shape / non-linear loads.
DCV basic accuracy 0.025%.
Noise filtering capability , Low Pass filter
low pass filter mode which filters out high frequency noise created by a variable frequency drives (VFD) and gives you an accurate reading
loZ
low input impedance prevents false readings due to “ghost voltage”.
Practical being used to verify if a wire is actually energized, Troubleshooting floating neutral or control wiring
low ohm measurement
Useful for measuring and comparing differences in motor winding resistance or contact resistance.
mV (millivolt) measurement
practical for measuring small signals, testing electronic components
4-20mA process loop measurement
troubleshooting 4-20 mA signal loops from a sensor
Logging function
The device has a built-in logging feature with plenty of memory,
You can look at the data as a graph directly on the device.
wireless connection, data share (PC / App)
Technicians can monitor readings remotely, which is especially useful when panels must be closed to operate or are in hazardous areas .
