FAQ | Handheld Tulip Contact Pressure Tester
Q1: What is the Handheld Tulip Contact Pressure Tester used for?
It is a portable measuring tool to test clamping force of tulip contacts and contact fingers on high voltage disconnectors. Regular testing prevents contact overheating, ablation and power system faults caused by insufficient spring pressure.
Q2: What is the maximum measuring range and test accuracy?
Standard measuring range is ≤1000N, measurement error ≤1%. It adopts aerospace strain gauges, featuring low temperature drift and excellent long-term stability.
Q3: Can the tester display pressure values in different units?
Yes. It supports switching between two units: Newton (N) and Kilogram (kg) according to user habits.
Q4: How many optional contact sensors do you provide?
Three types of interchangeable sensors are available for folding-arm disconnectors, universal tulip contacts and plug-in adjustable contacts. Custom sensors are also acceptable.
Q5: Does this device have an audible alarm function?
It supports voice alarm. When the measured pressure exceeds the preset threshold, the tester will automatically trigger an alert; users can freely set the alarm range from 0 to 1000N.
Q6: Can test data be saved and exported?
Built-in 8GB TF card stores data with timestamp in FAT32 format. You can export historical records to USB flash drive for archiving and report sorting.
Q7: What screen and operation mode does the instrument adopt?
Equipped with a 5-inch true-color LCD screen and 4-wire resistive touch keys, display content is clear and operation is simple for field technicians.
Q8: Is sensor zero calibration easy to complete?
Absolutely. One-touch zero reset function is reserved, users can finish sensor calibration and data clearing by themselves without professional tools.
Q9: How long is the continuous working time of the built-in lithium battery?
Fully charged battery supports more than 6 hours of continuous field work. It can also be powered by the matched external power adapter.
Q10: What working environment is this tester suitable for?
It adapts to wide temperature environments for outdoor substation maintenance, stable performance under harsh on-site overhaul conditions.
Q11: What after-sales services can overseas buyers enjoy?
We offer free remote technical guidance, one-year global warranty, lifelong maintenance and personalized configuration customization for various overseas high voltage switches.
Q12: What clock adjustment range does the real-time clock have?
The built-in high-precision clock can be calibrated, the adjustable date range covers from Jan 1, 1980 to Dec 31, 2099.
