Safety Information Read all safety and instruction statements before using the product. Failing to follow the safety guidelines can cause severe injury or death. Ampstik+ units are designed for use on live, overhead lines with 0 to 500KV. All procedures appropriate for the line voltage are to be taken, including proper work techniques, equipment, and Personal Protection Equipment. The Ampstik+ should be used only by certified personnel who have been trained for live-line, high voltage work by their organization. The hot stick length must be the correct for line voltage per minimum approach distances...

Take a Measurement in RUN Mode When in RUN MODE, the reading continuously changes as the current on the conductor changes. The unit is immediately in the RUN mode after powering on. To place the instrument into the RUN mode from a different mode, press and hold the control switch and scroll to the option RUN, then release the control switch to engage the option. Step 1: Attach the unit to a hot stick with a universal chuck adapter. Step 2: Power on the unit by pressing and releasing the control switch. STARTUP TEST The Ampstik+ conducts a startup test to verify the sensor and circuitry is functioning...

Step 3: Take a measurement. Place the Ampstik+ on the conductor as shown below, with the conductor positioned anywhere below the measurement lines on the arms of the unit. If the conductor cannot be placed below the bump-outs, readings are taken but the accuracy may be lessened. Step 4: Observe the readings being displayed on the unit.

Take a Measurement in HOLD Mode When in HOLD mode, the unit will automatically measure and hold up to four unique current readings Step 1: Attach the unit to a hot stick with a universal chuck adapter. Step 2: Power on the unit by pressing and releasing the control switch. STARTUP TEST The Ampstik+ conducts a startup test to verify the sensor and circuitry is functioning correctly. The following screens will display during the test: --If the test detects a failure, the display will show FAIL and a corresponding code as per below. See page 13 for the failure code chart. 1 If the test determines...

Step 4: Take a measurement. Place the Ampstik+ on the conductor as shown below, with the conductor positioned anywhere below the measurement lines on the arms of the unit. If the conductor cannot be placed below the measurement line, readings are taken but the accuracy may be lessened. Step 5: Hold the unit on the conductor for 2-4 seconds and then remove from the line. The measurement has been taken and the unit is ready to take the next reading. Each reading is numbered and displayed on the top left of the display. 1 Step 6: Repeat steps 4 & 5 to acquire up to three more readings. If the Ampstik+...

Display Resolution of the Measurements The unit will display to .1A in RUN mode and .3A in HOLD mode. The display resolution changes on the following ranges: 2000 to 5000 Amps 2.00 kAmps 10 Amp resolution (2 decimal places indicates kAmp range) Powering off the unit Step 1: Press and hold the control switch until the OFF option appears and release the switch. The unit is now powered off. The Ampstik+ will power itself off after approximately 20 minutes of inactivity.

Backlight The Backlight on the Ampstik+ is designed to automatically power on when the ambient light is low. This helps users view the display in low-light situations. The light sensor is located on the front of the unit. The user may see some flicker if the backlight is on when under artificial lighting By default, the Ampstik+ will start in Auto on/off mode on each power on. The modes may be changed manually during use of the unit. The unit will return to the measurement mode the unit was in before the backlight change. Backlight: auto on/off Press the control switch until the following screen...

Battery Replacement The Ampstik+ is powered by a single 9V battery. The battery should be replaced when the “LO BAT” indication shows on the display. To change the battery, loosen the screw on the battery cover at the rear of the unit. Pull the battery out of the compartment and install a fresh battery. Secure the cover by closing and tightening the screw on the battery cover. Cleaning The Ampstik+ can be cleaned by wiping with a silicone hot stick wipe to remove sand, salt, and dirt. High Voltage Operation This instrument is designed to operate in high voltage fields. However, difficulty may...

Troubleshooting the Ampstik Plus Unit will not power on Verify there is a fresh 9V battery in the unit. Backlight Flicker Due to the refresh rate of the light, some users may see flicker if the backlight is on when under artificial lighting. Fail Codes The unit will not enter into measurement mode if the self-test has any of the below failures. The unit will need to be returned to SensorLink for repair evaluation. FAIL CODE "1": Break to the main current sensor FAIL CODE "2": Break to a current sensor component FAIL CODE "3": Circuit failure FAIL CODE "4": Circuit failure Incorrect readings Verify...
