Why is my IQ Scientific Instruments Measuring Instruments showing no display?
The display might be blank due to a lack of power. Try replacing the 9V battery or using an AC power adapter. Alternatively, the auto power-off feature may have cleared the display; if so, press the ON/OFF key.
What does E01 mean on my IQ Scientific Instruments IQ240 Measuring Instruments?
If the meter displays the error code E01 after being turned on, it indicates a detected malfunction. To resolve this, turn the meter off, disconnect, and then reconnect the probe. Also, disconnect any cables connected to the RS-232 or analog ports. Then, turn the meter back on. If E01 persists, and the meter is used with the AC power adapter, turn the meter off, disconnect and then reconnect the power adapter, and turn the meter on. If the issue continues, turn the meter off, disconnect the AC power adapter, and turn the meter on using battery power only. As a last resort, replace the probe.
