What to do if Chroma Test Equipment shows OVER VOLTAGE protection (OVP)?
If you're experiencing OVER VOLTAGE protection (OVP) with your Chroma Test Equipment, it's likely because the Unit Under Test's (UUT) output voltage peak is exceeding the specified range. To resolve this, first turn off the power supply to the UUT. Then, verify that the UUT's output voltage is within the specified limits.
What to do if Chroma Test Equipment shows OVER CURRENT protection (OCP)?
If your Chroma Test Equipment is showing an OVER CURRENT protection (OCP) error, it means the sink current is exceeding the specified limit or the I LIMIT. The solution is to reduce the current.
What to do if Chroma Test Equipment shows OVER POWER protection (OPP)?
If your Chroma Test Equipment displays an OVER POWER protection (OPP) message, this indicates that the input power is exceeding the specification. To fix this, reduce the power or lower the input voltage/current.
What to do if Chroma Test Equipment shows OVER TEMPERATURE protection (OTP)?
If your Chroma Test Equipment is showing an OVER TEMPERATURE protection (OTP) warning, it could be due to a couple of reasons. * The ambient temperature might be too high. * The airway could be obstructed. To solve this: 1. Ensure the unit is operated within a temperature range of 0 to 40°C. 2. Check for and remove any obstructions in the airway.
What to do if Chroma Test Equipment shows INPUT FAIL protection on Chroma Test Equipment?
If your Chroma Test Equipment shows an INPUT FAIL protection error, it means the AC/DC load line input voltage is either too low or too high. To resolve this, measure the input voltage and adjust it if it's outside the specified range.
Why is the output distorted on my Chroma Test Equipment?
Distorted output from your Chroma Test Equipment can occur due to two primary reasons: 1. The input voltage is over specification. 2. The frequency of the Unit Under Test (UUT) is over specification. To correct this: 1. Program the input voltage within a reasonable range. 2. Program the frequency within a reasonable range.
What to do if Chroma Test Equipment shows UNDER operating VOLTAGE protection (UVP)?
If your Chroma Test Equipment is showing an UNDER operating VOLTAGE protection (UVP) error, it means the output voltage of the UUT is too low. To fix this, regulate the output voltage of the UUT to be higher than the specification.
How to fix Chroma Test Equipment when I cannot control AC load by GPIB?
If you're unable to control the AC load on your Chroma Test Equipment via GPIB, there are a couple of things to check: 1. The AC/DC load unit address might be incorrect. Update the address. 2. The GPIB cable might be loose at the rear. Check the connection and tighten the screws.
What does 'Out of Frequency Range (FREQ ERR)' mean on Chroma Test Equipment?
If your Chroma Test Equipment displays an 'Out of Frequency Range (FREQ ERR)' message, it indicates that the measurement frequency is outside of the acceptable range. To resolve this, ensure that the frequency of the Unit Under Test (UUT) is within the specified range.
How to improve V, I measurement on Chroma Test Equipment?
Poor voltage and current measurements on your Chroma Test Equipment can be caused by the aging of components, leading to deviations in their characteristics. Periodic calibration is required to address this issue.
