In the tables above, components prefaced with "C" are capacitors, resistors are listed with an "R" followed by the resistance value in Ohms, and potentiometers are indicated by the abbreviation "pot". Solder gaps are denoted by "SG". 3) Open the meter’s case to gain access to the printed circuit board. Low profile models are opened by snapping off the rear panel, using a screwdriver to carefully depress the retaining tabs located on the sides of the meter. Access to short-depth models is achieved by removing the cotter pin at the rear of the meter, snapping off the front bezel, and sliding the PC board forward. 4) Compare the PC board to the assembly drawing for that model as given in this document. Locate the component and solder gap locations which pertain to the desired modification. Note that some component locations will have no component installed. For example, Rl and R2 locations for all models do not have components installed. 5) Remove and replace components as necessary to achieve the desired modification. NOTE: WHEN MODIFYING UNITS TO THE 200V RANGE, IT IS RECOMMENDED THAT THE OPEN SOLDER GAP SG1 BE COV- ERED WITH CONFORMAL COATING. 6) After reassembling the unit, you may need to recalibrate the meter. This procedure is described in each meter’s data sheet. A generalized calibration procedure is as follows: a) Power-on the meter and allow it to warm up for ten minutes. b) Using a precision voltage source, provide a near full-scale positive signal to the meter’s inputs. c) Adjust the meter’s gain potentiometer (located at the rear) until the display is correct. d) Reverse the polarity of the signal input and check the meter’s reading. REPAIR RETURNS When returning a modified meter to DATEL for repair, the unit must be restored to its orignal ±2V input configuration prior to return. Damage to the meter caused by improper modification will void the unit’s warranty. MODEL 200mV RANGE MODIFICATION *For DM-4105/4106, Open SG4 (Leave SGl Closed).
