Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of "Caution", "Warning" or "Danger". They are all important notes for safety and must be followed in addition to International standards (ISO/IEC), Japan Industrial Standards (JIS)*1) and other safety regulations*2). *1) ISO 4414: Pneumatic fluid power - - General rules relating to systems.
Caution 1. The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
Operator ♦This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. ♦Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product. Precautions Warning ■Do not disassemble, modify (including change of printed circuit board) or repair.
■NOTE ○Follow the instructions given below when designing, selecting and handling the product. ●The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed. ∗Environment •Avoid using in a place where noise (electromagnetic wave and surge) is generated. This can result in malfunction (display of incorrect value), deterioration and damage of internal elements.

■Definition and terminology Terms A B D Auto power-OFF (function) A function that turns off the power supply automatically when no buttons are pressed for 5 minutes after the power supply is turned on. Auto power-OFF extension (function) A function that extends the time of auto power-off to 15 minutes. Back light A light that makes the display visible in a dark environment. Battery low display (function) A function that warns that the battery is running out by showing “L”.
Assembly ○Insertion of batteries Slide the lid of the case to open and insert the batteries into it. The type of battery that can be used is 2 A alkali dry cell battery (LR6). When inserting the batteries, pay attention to the polarities and insert them in the correct direction. After insertion, ensure the lid is closed for use. ○Mounting of the high voltage measuring handle 1. Insert the sensor. Insert the sensor to the handle in the direction shown in the right figure. 2. Fix the cable.
Setting / Adjustment ■Procedure 1. Insert the batteries in place. 2. Connect the ground wire. Connect the ground wire to a place where is connected to an external protective earthling system. The place where the ground wire is to be connected is as shown below. 3. Press the . 4. Get the sensor close to the position 50 mm away from the measured target.
■Function settings ○Power ON When the is pressed with the power supply off, the power supply will be turned on. All indications are displayed for 1 s. after the power supply is turned on. ○Power OFF When the is pressed for 3 s. or more with the power supply on, the power supply will be turned off. Also, no button operation for a certain period will turn off the power supply. (For details, refer to Auto power-OFF function.
○Peak/Bottom hold value When the is pressed with the power supply on, the indication will be changed to instantaneous value, peak hold value, bottom hold value and instantaneous value, in that order. ∗: Release the after "P" or "b" is displayed so as not to turn off the power supply. •Peak hold value The maximum charged potential and "P" are displayed. The maximum charged potential is continuously detected and updated from when the peak hold is started.
○Battery low When the battery voltage lowers, "L" will be displayed. The display will be done in a different way depending on how much battery is left. Display Content L (Flashing) The battery is low. Prepare for replacement with a new one. L (Solid on) The battery is very low. Replace with new battery immediately. ○Indicated digit change function The minimum indicate digit is changed depending on charged potential. ±1 to ±20 kV 0 to ±0.99 kV Min. indicate unit: 0.1 kV Min.
Troubleshooting ○Troubleshooting When the product is found to have operation failure, use the following flowchart to identify the cause of failure. If there is no cause applicable to the failure, consider the product itself has broken. The product can break for reasons in the operating environment. In such a case, consult with SMC about measures to be taken. The product does not operate normally There is no display Refer to reference No.
○Cross reference for troubleshooting Reference No. 1 2 Problem There is no display. The display appears, but immediately disappears. Possible cause Investigation method Countermeasure The battery is inserted Check the orientation of incorrectly. battery. Check the orientation of battery as shown in the case and if it is incorrect, reinsert the battery. The battery is running out. Check how much battery is left. Replace with a new battery. The battery is running out.
○Error indication function Error Name Error display Error Type Troubleshooting Method A charge over ±5%F.S. of the default zero point is given to the sensor during zero clear operation. (Er1) Zero clear error ∗: After approx. 1 s. error display, the sensor returns to measurement mode. Return to a condition without charge, and retry zero clear operation. This time will depend on the deviation of the product itself and ambient environment during zero clear operation.
