Instructions for fitting Current measurement adapter to DPM 951 or DPM

Configure DPM 951 or DPM 952 module for supply voltage, and annunciators. Configure anunciators as required,(mA, A etc) refer to
DPM 951/ 952 instructions. Configure the module for a 5V supply - DPM 952 -solder links 2, 3, 4, and 6 on rear of PCB (leave link 5
unsoldered) - DPM951 - solder links 4 and 6 on rear of PCB (leave link 5 unsoldered).
Note configuration of the supply voltage is necessary for adapters DMDA-951-ADP and DMDA-952-ADP. Complete Ammeter kits
DMDA-951 and DMDA-952 have the supply voltage links factory pre-configured.

Configuration

(Rear of DPM 952) (Rear of DPM 951)

Annunciator
Configuration

1) Fit the adapter module onto the rear of the DPM 951 or DPM 952 (depending on the adapter module). Configure the Current
Measurement input Selection switches for the appropriate range, and configure the Decimal point selection switches. Fit the rear case
as shown below.

Fit adapter module onto the meter

Cut out plastic from the rear case
to allow access to the connector
and fit onto the rear of the
DPM 95/ adapter assembly.

2)
Connect the power supply 0V output to terminal 1, connect the power
supply +5V DC output to terminal 2.
Connect terminal 3 to the 0V output of the circuit that current is to be

measured in. Connect the wire leading to your load to terminal 4 (The 0V
wire from the load)

It is possible to measure negative current on terminal 4. Terminal 3 must

be connected to 0V, not a -V or +V voltage.

Note, Do not apply a higher current than the unit has been configured for.
If a higher current is applied this may result in damage.
Connect the unit as shown in any of the three diagrams shown.
