Digital Anchor Dynamometer

First, the Digital Anchor Dynamometer

Product Introduction

The digital anchor dynamometer is a specialized testing tool used to measure the anchoring force of bolts. It plays a crucial role in both theoretical research on bolting and shotcreting techniques and in quality inspection during construction projects. The device comes in various specifications, including 5 Ton, 10 Ton, 20 Ton, and 30 Ton, allowing users to choose based on their specific needs.

Pressure Gauge Operation Method

1. Pressure Detection

Turn on the power key to display the initial value, then press the clear key to start measuring. Use the peak key to toggle between peak and follow values. When the display shows â–², it indicates that the meter is in peak hold mode, displaying the maximum pressure recorded during this measurement.

After completing the task, turn off the power key to shut down the display and power off the device.

2. Data Storage

While in peak hold mode, press the memory key to store the current peak pressure data. The display will show "SX", indicating that the data has been saved in unit X.

3. Displaying Stored Data

When in normal measurement mode, there is no â–² symbol in the top-left corner. Press the memory key to enter the stored data display mode. When "SX" appears, it means the storage is about to be displayed. After a few seconds, the meter will return to the normal state.

Common Faults and Troubleshooting

Failure Phenomenon	Cause	Solution
Pressure gauge no display	Lack of oil in the cylinder	Open the oil filling valve and refill
Unloading valve not tightened	Tighten clockwise
Joint oil leakage	Tighten the joint
Manual pump not placed horizontally	Place the pump level
Pressure gauge damage	Inspect or calibrate
No pressure	Insufficient oil in the manual pump	Add oil
Joint oil leakage	Check joints and seals
Incorrect or dirty oil	Replace oil
Hydraulic cylinder oil leakage	Internal seal damage	Replace the seal
Pressure gauge reading drops significantly	Severe joint leakage	Tighten or replace the seal
Seal failure	Replace the same type of seal
Oil is too dirty	Clean the oil cylinder, pump body, and pipes with kerosene and change the oil
Pump check valve sealing issue	Return to factory for repair
Pressure gauge shows reading but hydraulic cylinder has no pressure	Hose blockage	Clear the hose
Connector blockage	Clean the connector

5. Recalibration Procedure:

If you need to re-calibrate the factory-calibrated anchor tension pressure gauge, press and hold the clear key until three vertical symbols appear on the left side of the display and flash, then release. Press the clear key again to reset and begin pressurizing to match the standard pressure meter. For example, for a 100KN bolt dynamometer, reach 100KN, for 200KN, reach 200KN, and so on. Then press and hold the switch key until the three vertical symbols flash again, release, and clear. After zero calibration, check the pressure gauge to ensure accuracy.
