2. G eneral Des c ription This instrument provides all the equipment necessary to test and calibrate insulation test sets and megohm meters. It consists of a high precision resistance box, a volt meter and a milliamp meter. It is constructed from very high insulation materials, including its case, and is fully isolated from any external circuits including the mains supply.

Break before make self cleaning switch contacts.
4. Typic al Operation Ins truc tions 5069 Ins-Cal Typical Operation Procedure 1) Fully charge the battery in the 5069. 2) Fully charge the battery in the insulation tester (or fit fresh batteries). 3) Complete the set up procedure for the insulation tester (UUT = Unit Under Test). 4) Connect the selected test leads to the 5069 (these are 4mm recessed sockets). 5) Adjust the pointer at zero on the UUT (meter display, if required). 6) Select O/C VOLTAGE setting on 5069 panel.
5. 5069 Ins -C al P roc edural Notes 1. Always remove the battery charger leads from both instruments before starting set up. 2. Use only the measuring leads supplied with the Unit Under Test or those supplied with the 5069. When checking high resistance values the leads may pick up electrical interference, which can cause a disturbance to the readings obtained. Some manufactures fit a guard connection for use with dedicated leads, this will stabilize the readings. 3.
