BATTERY REPLACEMENT A low battery is indicated when the E2] symbol in the upper right hand corner is on. The low battery indication first appears when the battery is about 90% depleted. The meter may be operated a few more hours but the battery should be replaced soon thereafter. 1. Remove two screws from back of unit securing the tilt stand. 2. Remove tilt stand. 3. Remove two screws securing case back, then carefully lift back off to gain access to battery. Remove and save the bat- tery insulator. 4. Replace the dead battery with a fresh 9 volt transistor battery. Replace the battery insulator. Use alkaline batteries such as the NEDA 1604 or equivalent for longer life. To prolong battery life set the Function/Range switch to the OFF position when not making measurements. 5. Reinstall back cover, tilt stand. FUSE REPLACEMENT If no current measurements are possible, check for a blown over- load protection fuse. There are two fuses; F1 for the mA/pA jack and F2 for the 20 A jack. A quick check for a blown 20 A fuse can be performed by inserting the probe into the 20 A jack and setting the function switch to any other position except 20 A or OFF. If no warning tone is heard the fuse is probably blown. This procedure can be used for the 4A/mA jack fuse by inserting the probe in the pA/mA jack and setting the function switch to any position other than the OFF, A or mA positions. For access to fuses, remove the case back as described for battery replacement. Replace F1 only with the original type 2 A, 600 V, fast acting ceramic fuse (B+K Prectsion Part No. 194-044-9- 001). Replace F2 only with the original type 20 A, 600 V, fast acting ceramic fuse (B+K Precision Part No. 194-043-9-001). TEST LEADS Use only safety type leads, like those supplied. Periodically ex- amine the test leads to ensure that the conductors are not inter- mittent or broken. Also make sure that good contact pressure axicts atthe tect recentacles and faseholder. and keep these areas _ re NM ey ! & @2R owt 8 FPS ac OD 98 9 OL Bm @ > oO om o 6 a Av @ Do og + +O > 9 + 2 = - rx os ~ ne 2 m Ot Li x 3 2 snm se s g Q oO a 2 = g o eg 8 Bm be ze Ze + 3S ZEA aao FEATURES Complete Handheld Test Bench 11 Functions, 41 Ranges.

SAFETY An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts de or ac rms should be considered dan- gerous and hazardous since it can produce a fatal current under certain conditions. Higher voltages are even more dangerous. Observe the following precautions. 1. Do not exceed the following input ratings. Personal injury or damage to the instrument may result. DC VOLTS 1000 V (de Display: 3-3/4 digit liquid crystal display (LCD) with a maxi- mum reading of 3999 counts. Large 0.7 digits. Polarity: automatic (-) negative polarity indication. Overrange Indication: OL. Functional Annunciator: AC, DC, V, A, F, kHz, Q, hFE, and Logic $ on LCD display.

When an overrange is indicated (OL displayed) switch to the next highest range. | CAUTION | Do not switch between ranges while connected to a high voltage. AUTO POWER OFF 1. The meter will automatically shut off if the Function/Range switch position is not changed within 45 minutes. 2. To restore operation, rotate the Function/Ranges switch to any other position. VOLTAGE MEASUREMENTS 1. The annunciators in the lower left comer of the display indi- cate whether the ac or dc function is selected. The mV or V annunciator on the right indicates that voltage is selected. a. To measure ac voltage, set the AC/DC switch to the AC position. b. To measure dc voltage, set the AC/DC switch to the DC position. 2. Set the Function/Range switch to the desired voltage range. 3. Connect the red test lead to the -+ } V Q Hz jack and the black test lead to the COM jack. 4. Connect the test leads to the points of measurements. 5. For dc, a(-) sign is displayed for negative polarity: (+) posi- tive polarity is implied. RESISTANCE MEASUREMENTS 1. Set the Fanction/Range switch to the desired resistance range. 2. Remove power from the equipment under test. 3. Connect the red test lead to the ++ 4 V Q Hz jack and the black test lead to the COM jack. The red lead is (+) polarity. 4.
